Great resource that develops its techniques around different personalities
First thing I liked about this book is that it doesn't make the typical presumption that you have nothing else to do but commit your life to it's techniques. The idea is that you move toward your goal in a "tortoise approach" and sets you up with manageable goals applying yourself a little each day. And what seemed its most useful content was its discussion about various personality types and how to fit the practices to your own strengths and weaknesses. If you are looking to start a business, or write a book, even a large DIY project like add a room to your house, Acieve in 5 fits in perfectly with a life already in progress.
