Gentlemen should not waste their time on trivial games -- they should play go[3]
A man who does not forget an agreement is resolved and honorable man.
If there were an honorable way to get rich, I’d do it, even if it meant being a stooge standing around with a whip. But there isn’t an honorable way, so I just do what I like.
If you know, say you know. If you don't know, say you don't know.
Never tire to study. And to teach to others
He who is really kind, can never be unhappy
