"Making It All Work: Winning At The Game Of Work And The Business Of Life" by David Allen is a follow up and companion book to his widely popular "Getting Things Done." If you have read the first book, and want a little extra on the same principles, with some further guidance in them, you may enjoy this book. If you are looking for something completely different, or expanded on, you may be disappointed.
The book does repeat the same concepts, so if you have not read the first book, you won't be lost. There is a bit of a different framework with the principles he teaches, with different horizons of focus, which essentially is a way to look at the various areas of your life in the immediate to the larger long range picture. It's a good model, and if you do look at your life through these horizons, you will undoubtedly begin to define those activities that are important and what needs to be done to achieve your goals.
The book starts out with chapters on the GTD system, and the chapters on the main concepts of capturing, clarifying, organizing, reflecting, and engaging. Then there's a chapter on applying the concepts to life and work, followed by chapters on getting perspective on various levels of your life. It ends with a summary and description of making it all work in the real world.
Sometimes, people get caught up looking for the "new" or "better" system. If you purchase this book looking for that, after already having read "Getting Things Done," again you will be disappointed. However, if you are looking for a complementary text on the principles found in the first book, along with some repetition, but also with some additional direction, this book may fit the bill for you nicely. Especially if it has been a while since you read the earlier work and have drifted away from the application of some of the strategies and principles. The review and the motivating words in this book will help you get back on track.
I find reading these kinds of books help keep me on track. Even if I know the principles, sometimes I don't act on them. Reading books on productivity help me stay on track, and I also pick up little nuggets and gems that I incorporate into my planning, scheduling, and organizing to help me be more efficient. So I liked the book, and enjoyed the quick read and review.
