What Humans Can Learn from CPUs About Multitasking

What Humans Can Learn from CPUs About Multitasking

Multitasking

Nowadays, our minds and our computers are very busy, because we have more and more tasks to accomplish in the same amount of time. We are trying multitasking, but it seems human brains are simply not designed to operate that way! When you try to do two things at the same time, you know that is will not work long term, you can only focus on one thing at a time. That said, it is possible to deal with your tasks in a manner that appears simultaneous from the perspective of hours and days. This is effective multitasking, human edition.

We are now in multicore CPU era, but we can still remember the time that we had a single core CPU and yet had a multitasking environment. My old computer was able to play music, do some background calculations, and download a file from the Internet while I was writing a text at the same time. Multitasking operating system on a CPU that can do only one thing at a time: isn’t that exactly what we need? When we look how that has been achieved, there is a great lesson to be learned for humans.

Today, nearly all operating systems support preemptive multitasking, but there were early version of Microsoft Windows that were using cooperative multitasking, which didn’t work well. According to Wikipedia, “Preemptive multitasking involves the use of an interrupt mechanism which suspends the currently executing process and invokes a scheduler to determine which process should execute next.” Let us see what humans can learn about multitasking from that concept.

Lesson 1: Task switch is costly

What happens when task switch is initiated? We need to save the context with the intention of resuming the task at a later time. Save the context, resume another task, voila! However, it is not that easy for CPUs and it is even harder for humans. Saving context takes time and also CPUs have data cache, which stores recently used data for very quick access and switching the task will need to flush some of the cache entries. It will require some additional time to put that data back into cache. You know it probably all too well—a message pops up on your desktop when you are fully focused and it sidetracks your thought process; some cache entries are gone and it will take you minutes to regain your performance level. Lesson number 1 for humans is task switches are very, very costly!

If you react to pop-ups, enter your social media “just for one minute”, and look into your e-mail inbox every minute or two, you know why your performance suffers: your brain has to constantly save and restore the context and your “cache” is never efficient.

Lesson 2: Time boxes

Preemptive operating systems use a concept of a time slice, which is the period for which a process is allowed to run. An interruption, usually coming from a clock, will initiate a task switch. If you have a PC or Mac, this is how your CPU operates most of the time! This concept works great for CPUs, but it works even better for humans: the “Pomodoro technique” is a great example of that. I set my countdown timer and focus on just one thing. It is so powerful that it revolutionized the working style of many people.

I have all my data in very efficient cache, so my operation is very fast: I am avoiding task switches, but at the same I am sure that I will be able to accomplish all of my tasks, because my clock will tell me when to stop and/or switch. Every task switch is costly, and timeboxes are a great way to multitask effectively.

Lesson 3: Interval is carefully chosen

When using timeboxes, the main question is what intervals should I use? If it’s too short, we’ll use too much time on task switches, instead of the actual operation. When it’s too long, other tasks suffer. Can you imagine an operating system when task switch occurs every few seconds? That would be very unresponsive and annoying. The actual interval for our operating systems is usually several milliseconds.

With humans, the problem is more complex, because we are also getting tired. We cannot switch every minute, but three hours is also unrealistic; we would be very unresponsive, but also drained from energy at the same time. A good number to start with is “Pomodoro number”25 minutes—but your personal style, energy level, work demands will influence that. Experiment and see what interval works best for you. For CPUs and operating systems, that single number is one of the most important to determine whether it is going to be responsive and have a feeling of smooth multitasking.

Lesson 4: Interrupt handling

We are constantly dealing with interruptions in our work and CPUs handle millions of interruptions as well. What makes us very different from operating systems is that their interruption handlers are usually very, very quick and they do not require a context switch. You received a phone call, you read an email, you read a short message, and you changed a tab in your browser “just to see one thing”. It was not an interruption; it was a context switch.

If we dealt with interruptions in a similar manner that CPUs, we would simply write down some information, acknowledge that we’ve received it and resume an operation. It’s just few seconds. If it was an interruption, you did not have to switch the context. Do we really need that many interruption sources?

Lesson 5: Priorities

In operating systems, tasks have their prioritieseven interruptions have them. When handling an interruption of priority X, usually all the others with priority equal to or lower than X are blocked. It is a great lesson for us, because in many cases everything is equally important (and urgent!) and this is why we can rarely accomplish anything.

Summary

Humans are not CPUs. Our life is not about completing tasks effectively. We are spiritual beings; we have passion, emotions, relationships, and abstract thoughts. There is a great lesson that we can take from current CPUs and operating systems, however, and that is to multitask efficiently.

Try timeboxes to eliminate task switches, observe which intervals give you satisfaction and perception of effective multitasking, handle interrupts as interrupts should be handled and write down your priorities. When you think about multitasking, CPUs and operating systems are a great source of inspiration!

How to Be More Self-Assured and Get More Done During the Week

How to Be More Self-Assured and Get More Done During the Week

Time is a great leveler isn’t it? We all have the same 24 hours in a day. Even if you’re self-assured, the day may never feel quite long enough.

Why is it that some people can be so much more productive and achieve so much more in a typical day, while others struggle to achieve anything apart from feeling time crunched and overwhelmed?

Everyone I know and work with wants to make the best use of their time. They want to learn how to be more self-assured, happier, and work less—all while growing in their career.

How effectively we use our time—and how we actually work in our business—can make a huge difference to the amount we accomplish in a day or week. It can also make us more focused and more confident.

Do you want to have more thinking and creative time? Do you want to spend more time working on your business rather than working at or in your business? In this article, we’ll show you how.

Get More Done by Gaining Confidence

What if you had a strategy for making the best use of your time that brings you more joy and allows you to focus on the biggest activities and opportunities in your business? You may find the following outline below to be helpful:

1. Create an Exciting Vision

If you don’t know where you’re going, how do you know when you get there?

You want to be more productive and spend more time getting the right stuff done. Well, you need to create a compelling and exciting vision of your future.

What does this future look like? How will you feel when you get there?

Creating a new vision, especially one that is a lot bigger than where you are right now, has a way of igniting your passion. It may be something that feels hard to achieve, but every step you take towards that bigger vision will certainly build your confidence.

Create a vision board to feel more self-assured.

    Commitment to this vision, and accomplishing continual daily progress depends on your ability to look at any situation you’re faced with or currently in, feel self-assured, and see something bigger ahead.

    Also, when you know where you’re headed, you will instinctively start to see all the new opportunities and connections that will get you there.

    Make a vision map to get you started on the path to better productivity. This doesn’t have to be fully actualized, but you should know at least what direction you are heading.

    2. Build a Strategic Plan

    Once you have your future vision mapped out, the next step is to build a strategic plan to get you there.

    Your future vision may be for 3 years or 5 years, or you may choose a longer time frame. Any timeframe over 3 years may feel like a long way away.

    You may wonder how you are ever going to feel confident and motivated on this bigger future years from now when you feel as though you have so much to accomplish today.

    Advertising

    The first step is to decide on some specific goals for the next 12 months. Don’t list too many or you may begin to feel overwhelmed.

    The magic number for me and my clients is usually five annual goals.

    These are big goals that will create massive change in your business and life and bridge your current situation to your bigger future; accomplishing these goals one by one will help to increase your confidence on a daily basis.

    3. Get on Goal Planning

    Get yourself a piece of blank paper and a pen and divide the paper into 4 columns: A, B, C, and D.

    Ask yourself the question: What is great in my business and life right now? Write these things down in Column A. This might be a couple of things, five things, ten things, whatever feels right to you.

    Then ask yourself: What things are happening right now that I don’t want in my future? Write these things down in Column B.

    This is your opportunity to take a step back and look at the things that are simply not working. You may list people that are bringing you down or projects that you don’t want to work on any more. Maybe you’ll include a service offering that’s going nowhere. It could be the people you’re working with, or it could be your pricing.

    Now, let’s look at your personal strengths. Write down everything that you’re great at in Column C.

    These could be things that you’re doing right now and having success with. It could also be things you know you’re awesome at but you’re not spending enough time on.

    Column D is for your biggest opportunities. Is there a new service/product you could offer your ideal customers? Is there a new innovation you could bring to market? Just take some time out and really think and list these things in Column D.

    Once you’ve analyzed everything you’ve written down, take some time to really think about what goals you want to set for your business and life in the next 12 months.

    4. Set Outcomes to Build Confidence

    You now have your goals, and you’ll feel self-assured and raring to go. They are written down and you’re committed to achieving them. You feel self-assured and motivated.

    But how do you ensure that you stay on the correct course to achieve these goals?

    Managing and juggling day-to-day projects can get in the way. Dealing with problems can get in the way. Staying on top of orders, managing cash flow, and handling day-to-day stuff can move your ship off course.

    You want to be productive and achieve your goals, but you also need to ensure the day and week runs smoothly.

    One way to ensure this happens is to set 90 Day Outcome Goals; within those Outcome Goals, put some specific process goals that need to be undertaken.

    Let’s say you want to get 10 more speaking jobs in the next 90 days, and you know that you typically convert 50% of opportunities.

    Advertising

    Therefore, your process goal needs to be to have 20 conversations in the next 90 Days to deliver the 10 new pieces of work. You will then work out who you can have those conversations with.

    It’s smart to overshoot, so you will more easily hit your target. This is a clear plan to work through because with every win, your confidence will grow.

    5. Completely Commit to Your Success

    If you are not truly committed to achieving your goals, then chances are that you won’t reach them.

    Motivation can only take you so far. It is the intentional commitment[1] and emotional investment in your future success that will move you forward.

    Think back to any time that you really committed to achieving something. There must have been a reason you actually achieved what you set out to achieve. What motivated you?

    Were you fully invested? Why did it matter? Did you have to be really courageous to achieve it?

    How did it feel when you achieved it? What difference did it make?

    When have you felt truly self-assured? When you are committed to something, then you are propelled into action. Your mindset is focused, and your body follows; you want to get it done.

    And, when you do get it done, your confidence goes through the roof. You feel a level of certainty in achieving the goal you set out to accomplish.

    6. Focus on Your Strengths

    To feel self-assured and build up the confidence needed to achieve our biggest goals, we need to focus on our strengths.

    What are you best at? What are your unique skills? You want to spend as much time as you can working in the areas that you’re great at.

    Multiply your strengths. These areas are where you add the biggest value. They often bring you the biggest amount of joy, and you feel more and more confident when you are using your unique skills.

    If you think there is a specific capability you need to learn or be better at, spend more focused time in that area.

    Many of us want to do it all. We want to be good at everything. We want to offer a lot of services. But, in reality, there are some very specific things we are great at; nobody is good at everything!

    Spending more time adding value in the areas where you excel can create breakthrough results and boost confidence.

    7. Embrace the Present

    Sometimes we spend so much time thinking about the future or worrying about the past that we forget the present moment[2].

    Are you spending most of your day reacting to things, or have you taken the time to think about what your perfect day looks like?

    Advertising

    We all have the opportunity to create rather than react, to decide what we do with our day. All of our future success can be created in the present moment if we just take a step back and take action.

    Sometimes, doing it now is more important than doing it perfectly. There are hidden opportunities in every moment. We need to make sure we don’t miss them if we want to feel self-assured.

    8. Calm the Whirlwind

    The day-to-day life in business and life can be hard, which leads us to feel less self-assured.

    Your mind may be full to bursting with all of the things you feel you have to do. The phrase “I don’t have time” has almost become an instant reaction by so many people when new opportunities are presented.

    There is a whirlwind happening inside our minds.

    Appointments, notifications, tasks, phone calls, errands, cash flow, staffing issues, networking, marketing all can clutter up our timeline. The sheer volume of things we feel we should do creates procrastination, stopping us from pursuing the projects and people that matter.

    Many of us feel we have to do everything within our business.

    Rather than simplifying things and doing less, we do more. We work longer, which creates a lack of energy and focus. Because of this, we lose clarity on our biggest opportunities. If you feel this way, take some well-deserved time off.

    Look at where you’re spending your time. How much of your time is being spent moving your ideas forward?

    In the next 90 days, if you could delegate or outsource more daily tasks and spend more time focusing on where you add the biggest value, what difference would it make?

    Calm the whirlwind by slowing down and doing less.

    Focus on areas that you add the biggest amount of value. By doing this, your energy levels will increase, your confidence will grow and you will have more success.

    9. Take More Time off

    This may seem counterintuitive, but taking more time off to recharge and refocus can pay huge dividends.

    If you are constantly fighting fires and caught up in the myriad of different activities that you have to do each day, then how can you move your business forward?

    You may be being pulled in difference directions without any focused time on your biggest projects. If that’s the case, then it’s almost impossible to gain any real momentum in moving your business forward and hitting your goals.

    The best way to get off that treadmill is to take more creative time out of the business.

    Could you realistically take one day off per month to work on your business? If you could, what would you do with this time?

    Advertising

    Just imagine no distractions, only focused time on the strategic development and growth of your business.

    Every day off per month could have a different focus: New product innovation; Thinking about your biggest clients; Improving operations.

    Add to this a quarterly review to check in with your goals progress, and this could have a dramatic effect on where you spend your valuable time.

    10. Celebrate Wins

    Sometimes you just want to get through the day, right?

    You have so much to do. There are so many things on your task list that you just complete what you can and then start another day. But what would happen if, at the end of each day, you took some time out to look at what you’ve accomplished?

    Celebrating success keeps you motivated and helps you become more self-assured. It is not just another day. It’s a day that included things that should be celebrated.

    If you’re struggling to feel motivated, try celebrating a couple of wins each day.

    Celebrating success combined with the gratitude you have for achieving those wins will boost your confidence and inspire you for the next day.

    11. Give Yourself More Space

    When was the last time you gave yourself time to think?

    Within the hustle and bustle, it can be difficult to give yourself a little bit of space and time to just think[3].

    Imagine giving yourself just an hour a day to just let your mind wander or think about a specific thing.

    If you think about it, we can all free up an hour a day for something without really losing any efficiency or really impacting our business.

    In fact, that hour could be transformational for your business and life.

    A new idea for a product could form, or an idea for adding value to your existing clients could materialize. Perhaps you could do a check in to your ideal future and your goals. You could decide that you want to take your business in a new direction.

    Try this: Just sit alone for an hour with a notebook and let it be your creative thinking time. See what happens.

    Final Thoughts

    Ultimately, being self-assured happens when you have a clear direction.

    This, coupled with having clear goals and working in your unique skill-set, gives you the biggest opportunity to be more productive and get more of the right things done.

    The old mantra that “less is more” is right on the money. By giving yourself more time to work on your goals, you will inevitably increase your confidence; at this point, your ideal future can be anything you want it to be.
