I read this book few months back. It is short and I completed it within few weeks. I was curious to know about subconcious mind features and powers but I was just able to develop faith in that book. There was no way one can make success just by thinking it in morning and night.
I was not happy with the method described in the book. it was just not practical for me. The way author want to describe the power of your mind is just unusual and did not work at all.
As a recommendation I would not recommend it to any one as it gives just false hopes and is not practical.
