Query: Turned on my light bulb!

What Jack Zufelt had to share in this book should be required reading for anybody who wants to get more out of their life.This book was like a 10,000 watt lightbulb going off in my head - showing me why I have been struggling and more importantly how to change things around and live the life I really want. And so far the results have been nothing short of incredible. I have almost doubled the income in my business in the past 45 days, reconnected with family members and have never been so excited about my life.I can't recommend this book enough, it is truly different from all of the other books out their about motivation, success, etc. This one actually works!
