In counseling thousands of people and in consulting with hundreds of corporate executives, Tim Timmons discovered 7 maps to total satisfaction that will help you navigate around the "parasites" that are sucking the life out of you.
I spent a significant amount of time with Tim in 2005-2007 and this book is a very spot on guide to living a life of balance. If you ever find yourself trying to improve an aspect of your life but can't succeed, it's probably because you don't understand that you have to consider the other aspects of your life and how they interact.
