I attended one of David's seminars in 1986. As a result, I was able to successfully manage 101 concurrent projects, finishing on time and under budget. Fast forward to 2001. I keep this book by my side at all times (David publish it in Ebook form so it's easier to carry!). The company I'm with now wonders how I get the "impossible" projects done. Using David's techniques in the book, it seems like I can complete a full work day in fewer hours because I know what all my "next actions" are, and do them promptly. Gives me a lot of worry free time. This is a book you "DO" not just read. Be prepared to work when you start out, but when the initial work is done, that's when the fun begins. I cleaned my inbox and email box of 300 items in less than 15 minutes, filtering out the junk, the things that needed immediate attention, and the "someday maybe" things (like buying my first Harley). This works for my personal life too. No more missed anniversaries, birthdays, phone calls, errands, etc. Do you ever think about work projects at home? Do you ever think about home projects when you're at the office? Ever worry about that phone call you need to make or that errand you need to run? Forget it! Get the book. It's awesome. Get the book - period. If you don't, you deserve your stress.
