For people who have started to use GTD (Getting Things Done), make sure drop by Goncalo Moura’s Squidoo Lens on GTD. You will get some overviews and links:
Getting Things Done, or GTD for short, is an organization methodology developed by David Allen. GTD proposes getting all of the pending “stuff” you have in your head into a trusted system, with defined rules, and breaking them into a set of next actions, to be done sequentially.
From David Allen’s GTD book:
“Get everything out of your head. Make decisions about actions required on stuff when it shows up – not when it blows up. Organize reminders of your projects and the next actions on them in appropriate categories. Keep your system current, complete, and reviewed sufficiently to trust your intuitive choices about what you’re doing (and not doing) at any time.”
