I am sorry that someone has died, and I regret making a comment on this particular post before realizing the actual post topic too late, but I am not too keen on living my life based upon how billionaires think. Munger, like many billionaires and as the above quote and his dorm designs showcase, liked to speak about things he didn't know anything about, and people like to idolize billionaires in hope that they will someday be one too.
Self-pity is a natural human emotion. Rejecting it outright and replacing it with self-blame seems beyond strange. I would recommend people to sign up for a therapist and have a professional help them work through life rather than a person only well known for hoarding capital and opining on things he isn't educated in.
