I have read and own a lot of self-improvement books, this is the only one that has really propelled me into action. The short exercises in each chapter are well structured to enable you to learn about yourself and reasons behind your self-imposed limitations and gives great techniques and practical advise on how to overcome them, while also challenging you to think a lot about why you behave the way you do. I don't like writing in books usually - but this one is more of a workbook for myself now, so if you want to really give yourself a good shot at making some life changes - then this is the book for you.
