Nothing incites to money-crimes like great poverty or great wealth. - Mark Twain

If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed.

There is no sadder sight than a young pessimist.

Unconsciously we all have a standard by which we measure other men, and if we examine closely we find that this standard is a very simple one, and is this: we admire them, we envy them, for great qualities we ourselves lack. Hero worship consists in just that. Our heroes are men who do things which we recognize, with regret, and sometimes with a secret shame, that we cannot do. We find not much in ourselves to admire, we are always privately wanting to be like somebody else. If everybody was satisfied with himself, there would be no heroes.
