This is the most effective book which supported me to solve my decision making problem and understand when and why I made wrong decisions.After finishing this book,I met with my freedom and being happy and enjoy the life.If you want to change your character or behaviors,this book is the best guide in my opionion.Changing character is possible if u know what do you wanna change and you know what is your problem.First you have to change your thoughts cuz your thoughts are affecting to your behaviors,your behaviors transforming to your characters and your characters controlling your mood and life.I recommend you to read this book 10 pages per day, analyze and take result what you are reading,repeat everyday to perceive the content because it’s slow and heavy book.It’s around 600 pages,take it as 2 months treatment to meet your comfort.after 150 pages you will see a lot of progress but I highly recommend to read it until the end and be more flexible on your mind and gain the best confidence of yourself! Goodluck to everyone,I hope it will help you and change your life by this amazing book!
