I'm not typically interested in self-help titles, but Getting Things Done is literally making it easier for me to be more productive. I've still got a ways to go in figuring out a system that works for me, but this book is a tremendous help. "From core principles to proven tricks, Getting Things Done has the potential to transform the way you work - and the way you experience work. At any level of implementation, David Allen's entertaining and thought-provoking advice shows you how to pick up the pace without wearing yourself down."
