By Nathaniel Branden. I read it in Spanish. I received this book as a give some years ago. Im not so much in to self help books, because I think most of them are too superficial or write it by people without the training to work in human behavior.
But this book is very good. Nathaniel make a radical change about my concept of self esteem. Also is very practical, a lot of “complete sentences” exercises. I love it. I already finished this book, but now im going to start it again to complete the homework. 7 minutes ago
