Be cautious and bold.

When there is blood on the street, I am buying.

Sacrifice money rather than principle.

Faithfully guard your reputation.

Make few acquaintances.

Never have anything to do with an unlucky place, or an unlucky man. I have seen many clever men, very clever men, who had not shoes to their feet. I never act with them. Their advice sounds very well, but they cannot get on themselves and if they cannot do good to themselves, how can they do good to me?
