Query: Its use is changing my life!!

Love the CD set, as my lifestyle doesn't allow a lot of reading. It contains everything I've already learned about the power we all have within us. So much better than piecemeal. Those who use the techniques within will change the world. I'm already seeing it in the lives of those who know. I've been listening to if for two weeks now and experience the results everyday. I'm ordering a set for my daughter now.
