Great advices true nice stories, im giving it 2 out of 5 stars becouse author has writen one whole part of the book about how history should not be used as a predictor of the future and is saying in the very end that current economic situation in world is the same which lead to darkest event in human history which happened in 20th centuary and that it may again lead to that. So he his not foollowing his own words and advices which means he lacks Integrity so final review is 2.
