Much of the stress that people feel doesn't come from having too much to do. It comes from not finishing what they started.
David Allen
When you "have to get organized," you're probably not appropriately invested yet in what you need to get organized for.
David Allen
Here's how I define "stuff": anything you have allowed into your psychological or physical world that doesn't belong where it is, but for which you haven't yet determined the desired outcome and the next action step.
David Allen
First of all, if it's on your mind, your mind isn't clear. Anything you consider unfinished in any way must be captured in a trusted system outside your mind, or what I call a collection bucket, that you know you'll come back to regularly and sort through.
David Allen
