“Know your numbers’ is a fundamental precept of business.”

I should say in general the advantage of education is to better fit a man for life’s work. I would advise young men to take a college course, as a rule, but think some are just as well off with a thorough business training.

Always do business as if the person you’re doing business with is trying to screw you, because he probably is. And if he’s not, you can be pleasantly surprised.

The only question with wealth is, what do you do with it?

It has always been my rule in business to make everything count.

Be patient with me, dear heart. The art of loving is a peculiar business when one has spent an eternity hating themselves.

All I say is, nobody has any business to go around looking like a horse and behaving as if it were all right. You don’t catch horses going around looking like people, do you?

Avoid, as you would the plague, a clergyman who is also a man of business.

I’ve got to keep breathing. It’ll be my worst business mistake if I don’t.
