Query: This book changed my life!

This book is filled with words of wisdom. You will want to read it more than once to absorb it all. This book has changed my life. In the first week of implementing my rule, I had more time than I ever imagined to spend with my children and in prayer. Without a doubt one of the best, life-changing books I've ever read. Worth EVERY penny.
