Write what you like; there is no other rule.

The first rule of business is: Do other men for they would do you.

Whenever he saw a dollar in another man's hands he took it as a personal grudge, if he couldn't take it any other way.

By rights you're a king. If I was you, I'd call for a new deal.

I had also lived by the rule that if some is good, more is better.
