I found this book really helpful - it didn't look as promising as some of the more glossy books initially, but the content is great. The principle (basically keep things where you use them, so they are easy to put away again) is basic common sense but most people don't actually follow it. Sheila Chandra has managed to expand this concept into a book by providing loads of detail about HOW to implement it, and the right habits to develop to keep it that way. Forget the lists, detailed routines, etc that other books suggest, this is an easy, practical way to keep things in order and still have loads of free time. The system for staying organised and managing your time at work is aimed at those working from home, but equally applicable to any workplace; again, this sounds like common sense but if you actually try it you see how powerful a technique it is. Highly recommended!
