I read the reviews here before purchasing the book. I had read that it took good math skills, and since I've always had a good head for math, I thought I would be able to get the program with no problems. I was able to follow his instructions, but my rational could not grasp why I was doing some of these excercises. I mean, if he stated that we are doing this step so we can figure out blah blah blah to take it to the next step, I would've probably kept going. I found myself making lists, and charts, and not knowing what I was supposed to do with them, and when I got to the next step, couldn't figure out how the last step applied to the new step. I found this book very difficult to grasp, and I'm either going to send it back, or give it away. However, I did come up with my own little system out of doing some of this, so it wasn't a total loss, and that is why I gave it 3 stars. The whole book didn't suit me, but part of it gave me some inspiration. If you don't have a mind for complicated details and charting, this book isn't for you.
