Never trust the advice of a man in difficulties.

Never have a battle of wits with an unarmed person.

Never test another man by your own weakness.

Never ask advice of someone with whom you wouldn’t want to trade places.

Never attempt to reason with people who know they are right!

Don’t criticize what you don’t understand, son. You never walked in that man’s shoes.

Whatever you do, never waste your thoughts on other people’s ill-informed opinions and guesses.

Never argue with an artist.

Never complain, never explain. Resist the temptation to defend yourself or make excuses.

It certainly is no proof that a man is inspired simply because he is right.
