As a product of the ideal that was perfection.
Since I was a child (approx. 7/8yo) I would notice everyone's flaws (subjective opinion, I know) and adapt my personality so that I don't conform to those flaws. I would also take into account the disliked characteristics of human behaviour and ensure that my personality lacked those. It's funny how after years of conditioning/brainwashing myself I genuinely don't care what others think about me anymore. I'm glad I went through that process, though.
