Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no hope at all.

Just because something doesn't do what you planned it to do doesn't mean it's useless.

Failure doesn't mean you are a failure it just means you haven't succeeded yet.

An economist's guess is liable to be as good as anybody else's.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.

No enterprise is more likely to succeed than one concealed from the enemy until it is ripe for execution.

I am certainly not one of those who need to be prodded. In fact, if anything, I am the prod.

It usually takes me more than three weeks to prepare a good impromptu speech.

Effort only fully releases its reward after a person refuses to quit.

If all the economists were laid end to end, they'd never reach a conclusion.
