Getting Things Done - The Art of Stress-Free Productivity by David Allen
I thought that this book would just be another 'self-help' style tomb that showed you how stupid you were because you didn't understand the basic rules of the universe, but to my surprise I was wrong.
The book actually involves creating a workable 'to do' process that can be use in all areas of your life. The solution is simple but requires a mapping of the workflow of things that need doing as they come. The process then moves from accumulation of these items to actually dealing with them.
Now, although not a revolutionary process there was plenty of ideas and encouragement that I took away from the book. You can't necessarily implement everything the book deals with but for me, there are some real nuggets of gold that I can being to implement immediately. There are also plenty of things that I'm going to have to go away and have a think about as I need to implement them in the manner which I currently operate.
I wouldn't recommend this book as light entertainment or something to read before you go to bed, it requires too much involvement for that. However, if you are serious about improving your productivity and examining the way that you actually do things then this book is worth a read.
