At first I sought self-esteem through accomplishments, especially at university. This was very useful for my career and led to becoming a theoretical physicist, but in retrospect the accomplishments did not really increase my self-esteem.
More valuable was studying philosophy and meditation, because these activities changed me into a more likeable person. I became less judgemental, more consistent and deliberate in my thoughts and actions.
Now my self-esteem comes from being in a position of fundamentally liking myself, and also being satisfied by my accomplishments. I don't think it would have worked out as well if I just did philosophy without advanced training in mathematics; in Plato's republic, he recommends advanced study in science and math for several years before beginning the study of philosophy, and I think that is a good way, though perhaps not the only way.
Edit: I am a libertarian when it comes to judging others. I think every lifestyle is equally good (I believe someone who donates their time to disadvantaged children is just as good of a person as a man-child who plays video games on his Mom's couch all day; the person helping children is much more useful and deserves to be paid more, but he is not a better person).
As an ethical libertarian, I accept any lifestyle that does not infringe on the personal freedom of others. Drug users are fine, prostitutes are fine, religion is fine, atheism is fine, gays are fine, furries are fine, etc. The only things that are not fine involve violence or coercion of unwilling people - and minors or invalids who can't necessarily make responsible decisions for themselves are a special case.
