If you don't say anything, you won't be called on to repeat it.

You can't know too much, but you can say too much.

In the discharge of the duties of this office, there is one rule of action more important than all others. It consists in never doing anything that someone else can do for you.

You know, I have found out in the course of a long public life that the things I did not say never hurt me.

I have found it advisable not to give too much heed to what people say when I am trying to accomplish something of consequence. Invariably they proclaim it can't be done. I deem that the very best time to make the effort.

Never go out to meet trouble. If you just sit still, nine cases out of ten, someone will intercept it before it reaches you.
