Courage to be Disliked Book by Fumitake Koga and Ichiro Kishimi

I read it sometime back. It questions the idea that our childhood events have formed our current personality and our behaviour. It asks us to reinterpret the past events from different perspective. It encourages everyone to live in the moment and form a mindset to change for better where we compare ourselves with our ideal self and look at each other as comrades and not as enemies in a zero sum game.
