How Useful Is the Pareto Principle?

How Useful Is the Pareto Principle?

The Pareto Principle states that 80% of the results from any series of actions are caused by 20% of the actions themselves. In other words, most of the results we get are because of a small minority of our actions. The rest are either wasted or produce little of value. This sounds like a useful observation. However, before you decide the Pareto Principle is true and can be used to guide your actions, I want to ask two important questions.

  1. Can you identify which actions make up the useful 20%? And can you do so in advance?
  2. Does this useful 20% always contain more or less the same actions?

Let’s take the first question. It’s easy to feel intuitively that most results arise from a small group of actions. The Pareto Principle feels immediately valid. It also feels like a practical tool. Identify the “magic 20%” of actions and you can more or less dispense with the other 80% without much impact on your results. What a marvelous saving of time and effort.

Of course, this only works if you can reliably distinguish the 20% of actions (or people, or events) that produce that disproportionate amount of benefits. It also assumes every result comes from a single, identifiable action — or at least a small, obviously linked group of them.

But is this true? Don’t some results rely on the interaction of large numbers of events, choices, actions and decisions? Can we know which count and which don’t? What if we dropped some, only to find later they were essential in some way? Maybe they only produce good results in combination? Cutting seemingly unnecessary actions because they don’t obviously fit into the “magic 20%” might turn out to be a poor idea.

The Pareto Principle is perhaps most often applied to sales. Suppose you could reliably identify the 20% of sales calls that produced 80% of the orders you took this week. How much might the success of those calls rely on the market intelligence, knowledge and simple practice you gained by making the other 80%? Could you miss out all the rest, or even a significant number of them? That would include new customers being encouraged to place larger orders, prospects and old customers who might be won back from a competitor.

My second concern is this: is it always the same 20%?

Advertising

Let’s stick with the sales calls. This week, 20% of your calls produce 80% of your sales. Pareto rules! Next week, you need to sell just as much. Will you visit the same 20% of customers and receive the same orders?
Surely that’s unlikely. They only just placed an order. Most, maybe all, need to use up that order before buying again. Fine. You just need to find another 20%. But how? Everyone else was in the “unproductive” 80% last week? But if Pareto works, at the end of the next week you’ll once again find 80% of orders came from a new 20% of calls.

What’s going on? My guess is the Pareto Principle distinguishes groups you can only find after the event, once you can see what worked and what didn’t. The membership of the “magic 20%” of people or actions shifts each time. Wait long enough and every one will sometime be part of that 20% group.

If that’s so, the Principle is almost worthless as a guide to future action, which is how it’s most often used. There may be some actions or people (20% again? Who knows?) that figure so rarely in the “magic group” they could be removed without loss. There may be some regular members of that group that could be identified and given more focus and investment. Either way, what’s needed is time, careful observation and recording over many occasions, good records and much patience and reflection. None of these are actions or qualities much associated with today’s frenetic organizational pace.

I’m not saying Pareto is wrong. I don’t know. I’m not sure anyone has ever done the lengthy and extensive research needed to find out. I’m merely suggesting it’s neither the universally applicable principle, nor the simple measure, nor the practical guide to decisions we’ve been asked to believe it is for so long.

To sum up:

I think the Pareto Principle has great intuitive attractiveness — which says nothing about whether or not it works, nor how it works (if it does). However, these questions remain unresolved:

Advertising

  1. How do you know which 20% is producing the results? Can you even find out at a time when the knowledge might be useful? I suspect you can usually only find the answer — if there is one — after the event. And if that’s so, it leads me to a second question.
  2. Is it always the same 20%? If it’s not (and I suspect it isn’t), over time maybe the whole 100% will be in that magic 20% group sometime. And if that’s true, the Principle applies only to a specific occasion (if it applies at all).

If any of my concerns is valid, the whole idea becomes worthless as a guide to future action or allocating resources (which is how people try to use it).

7 Natural (And Highly Effective) Ways to Improve Memory

7 Natural (And Highly Effective) Ways to Improve Memory

How is your memory? Is your cognitive function as strong as you’d like it to be?

If not, then you’re definitely going to be interested in the memory improvement tips I’ll be sharing with you in this article.

Despite what you might think – or have been told – improving your ability to recall information is certainly possible. You just need to know the right ways to do it. (Don’t worry, as you won’t need to make any significant lifestyle changes.)

So how to improve memory? Let’s dive straight into the first of seven easy ways to improve your memory significantly.

1. Meditate

We live in a world of non-stop, 24/7 information. It’s like a waterfall that’s endlessly pouring news, data, facts and figures into our conscious minds.

Unfortunately, our brains are not designed to absorb this tremendous amount of information. It’s no wonder then, that most people struggle to remember information and recall things.

Even if you believe you have a good memory and are comfortable with multi-tasking, you’ll also be aware that there’s only so much information your brain can process at one time. And research suggests that the more information and distractions, the harder it is for you to transfer information to your long-term memory.[1]

Fortunately, meditation can help you out.

Even if you just meditate for 10 minutes per day, you’ll boost your ability to focus, which in turn, will make it easier for you to remember important facts.

If you need help in shifting into a meditative state, I recommend trying an app like Headspace – which can assist you to achieve this in a convenient and structured way.

And don’t forget, meditation doesn’t just have to be closing your eyes and sitting in a lotus position. Some people prefer to simply take a short walk in nature. This clears and calms their mind, and still provides the all-important boost to their focus.

2. Get plenty of sleep

If you’re sleep deprived or have not been sleeping well, then I’m guessing you’re not remembering well either. This is because sleep and memory are intimately connected.

If you have a busy life and regularly find yourself not getting enough sleep, then this will negatively impact your cognitive abilities – including your memory.

How much sleep should you be getting?

Well, according to the National Sleep Foundation, you need a minimum of seven to nine hours of sleep per night. If you get this amount of sleep regularly, then within just a few days, you’ll see a tangible improvement to your ability to remember and recall things.

Now, I’ll be honest with you, maintaining a proper sleep cycle is not always easy (especially when the latest Netflix series has just been released!). But if you care about improving your short-term and long-term ability to remember things, then it’s critical that you try to get at least the recommended amount of sleep every night.

Are there ways to hack the sleep cycle?

Yes, there are.

Try these three things:

  • Have a fixed bedtime (preferably before 10pm)
  • Don’t eat too late
  • Make sure your bedroom is as dark as possible

Sleeping is a precious activity. It regenerates your body, clears your mind, and helps with the storing and retrieval of information.

However, don’t sleep just yet, as I want to tell you about another great way to increase memory…

3. Challenge your brain

When was the last time you challenged your brain?

I don’t mean challenged in the sense of overeating or undersleeping. I’m referring to stretching your mental capabilities through things like crossword puzzles, Sudoku and memory games.

To expand your memory bank, and to make your recall razor-sharp, you need to continually challenge your brain.

Feedback from Lifehack readers such as yourself, has suggested that brain training apps are a super-effective way of doing this. Used regularly, these apps can enhance your focus, attention span, problem-thinking ability and memory.

There are hundreds of these apps available (most of them for free), but I recommend starting out with one of the big three:

  • Peak (Android/iOS, free, 10 million+ downloads)
  • Lumosity (Android/iOS, free, 10 million+ downloads)
  • Elevate (Android/iOS, free, 5 million+ downloads)

If you normally spend a chunk of your week playing computer games, then instead of shooting and killing your enemies, why not let some of them live – while you put your attention into boosting your brain power!

Challenging your brain will strengthen your neural pathways and enhance your mental abilities. But don’t just take my word for it, try one of the apps above and see the positive benefits for yourself.

4. Take more breaks

When I think back to my days as a budding entrepreneur, I distinctively remember working all the hours under the sun – and many under the moon too!

At that time, I believed that breaks were for the weak, and to become wealthy and successful, I needed to shed blood, sweat and tears.

However, I was wrong.

Taking regular breaks is the best way to keep yourself productive, creative and alive to opportunities. It’s also the best way to learn new information.

Let me explain.

Typically, when studying lots of new information, most people will spend hours reading it – in an attempt to learn and remember the content as quickly as possible. Unfortunately, they’ve overlooked something.

Namely, extended study sessions are rarely a good thing, as your ability to retain information naturally declines after a certain period of time.

It’s similar to physical exercise. You wouldn’t attempt to train vigorously for four hours in a row. Instead, you’d take regular breaks to give your lungs, heart and muscles adequate time to recover. Failing to do this will result in muscle cramps and overexertion.

It’s the same with your brain. If you overload it with information, you’ll suffer from mental fatigue.

What’s the answer?

Make sure you take regular breaks when learning new information. I recommend at least a 10-minute break every hour. (You may also want to take a look at the Pomodoro Method.)

If you don’t want to be as regimented as that, then take breaks as soon as you find yourself losing the ability to focus on the new material. Your brain will thank you – and your learning aptitude will move up a level.

5. Learn a new skill

I love this quote, as it’s 100% true – but frequently overlooked:

“Learning never exhausts the mind.” – Leonardo da Vinci

From my experience of helping to develop the careers of dozens of Lifehack employees, I can definitively say that participating in meaningful and purposeful activities stimulates the mind. It also reduces stress and enhances health and well-being.

Let me give you an example of this:

Imagine you work for a global financial institution in one of their call centers. You take over 100 calls a day – many of them complaints. When you started the job a few months back, you were excited to be in full-time employment and working for a household name.

Unfortunately, your initial enthusiasm quickly turned into frustration.

The endless complaint calls began to take their toll on you. And the supervisors irritated you too, as they were far too interested in micro-managing you – rather than letting you work in your own way.

Now, in the story above, the ending could be that you put up with a job you didn’t like, and led a dull and frustrated working life for years and years. However, an alternative ending is this: you channeled your dissatisfaction in to learning a new skill (computer coding). It took you a year or two to get up to speed, but it allowed you to successfully upgrade your career – and the ongoing learning made the call centre job much more bearable.

Clearly, learning new skills gives you impetus, focus and something to aim for. Your brain loves to learn, and you should tap into this by always seeking our new information. And when learning becomes a habit, you’ll find your ability to remember and recall things effortlessly, becomes a habit too.

6. Start working out

If you’re not already working out regularly, then here’s another reason to do so:

Exercising for 20-30 minutes three times a week will improve your long-term memory.

Regular exercise increases blood flow in your body and supplies the brain with extra oxygen and nutrients. And a well-nourished brain is a well-functioning brain!

“But I just don’t have the time?,” I hear you say.

Not a problem.

A research has shown that a daily burst of 60 seconds of high-intensity exercise, offered many of the benefits of the longer exercise routines.[2] So, if you’re short on time – now you know what to do.

Here are five different ways that will help you work out:

  • Join a gym
  • Join a sports team
  • Buy a bike
  • Take up hiking
  • Dance to your favorite music

7. Eat healthier foods

I’m sure you’ve heard the expression: “You are what you eat.”

This applies to your brain too.

The food that you eat helps determine your brain’s capacity to store and recall information. A poor diet (think junk food + soda!) harms not just your physical health, but your mental health too.

Fortunately, there are several foods that are especially good for your brain and your memory. These include: blueberries, celery and dark chocolate. But anything high in antioxidants will have a positive effect on your brain and memory.

Conversely, highly-processed foods and those loaded with sugar will have a negative impact on your memory. This is due to them providing insufficient nutrients for your brain – leading you to easily suffer from mental fatigue.

Want to be mentally healthy? Then eat and drink an abundance of these for brain health:

  • Turmeric – helps new brain cells grown
  • Broccoli – protects the brain against damage
  • Nuts – improves memory
  • Green tea – enhances brain performance, memory and focus[3]
  • Fish oilfish oil supplements can increase your brain power

Here’re more brain food options that improve memory!

Final thoughts

I sincerely hope these seven memory boosting ways that I’ve covered in this article will be of help to you.

You don’t need to implement them all. I suggest just trying the ones that appeal to you.

But, if you’re serious about dramatically improving your memory, then make a start right now on adopting one or more of the ways I’ve suggested. I’m confident you won’t regret it.
