Getting Things Done: the Art of Stress-Free Productivity
David Allen 2001 Penguin Books
David Allen's book on task management walks you through his straightforward strategies for getting and keeping your work under control: identifying all of the tasks you need to do, deciding what needs to happen next for each task, and organizing those tasks. His fundamental premise - that you can't make the best choices about what to do next until you know what all of your choices are - is simple, but powerful. Once you have a handle on all of the tasks demanding your attention, you'll be able to make appropriate choices about what to do next.
