The book is biased and leads one to do inaccurate thinking. It also encourages a person to do post mortem on what went wrong.
And a point which I did not agree about was bullies have low self esteem. I do not agree with that at all because bullies are people with high self esteem and they feel really good about themselves. They think they are charismatic and cool and are extremely confident.
So, because of all this I wouldn’t recommend this book to anyone.
