So you're saying that we should not or can not learn from the experiences of others. The idea that most people are wired roughly the same holds no sway with you, and that only personal experience can possibly show you how things work. This means you never take into account reccomendations for movies, or books or restaurants. Never learn from others' mistakes right? Thats what you are saying. Of course none of the above takes into account the fact that you are biased to judging yourself well (my actions were of course right). Your analysis could be based on some flawed assumption (the happiness i get from X is the maximum of happiness, maximizing the little happinesses reaches a global maximum, not a local one, etc). Or that other people could possibly know more than you. Not that this comment matters, only your judgment and thoughts could possibly be correct in the end.
