While the young author expresses his opinion quite well, many more issues go into making you happy. It's not as simple as do it or don't do it. This book is a starting point. You will learn more about yourself as you read through this book.
I did find issues. The book is very repetitive. The author points out all the negative but doesn't balance it with positive comments. I was unimpressed with this book.
I gave this one 3 cheers out of 5.
