I often say that research is a way of finding out what you are going to do when you can't keep on doing what you are doing now.

The opportunities of man are limited only by his imagination. But so few have imagination that there are ten thousand fiddlers to one composer.

I expect to spend the rest of my life in the future, so I want to be reasonably sure of what kind of future it's going to be. That is my reason for planning.

I could do nothing without my problems; they toughen my mind. In fact, I tell my assistants not to bring me their successes for they weaken me, but rather to bring me their problems, for they strengthen me.

Research is an organized method for keeping you reasonably dissatisfied with what you have.

If a fellow wants to be nobody in the business world, let him neglect sending the mailman to somebody on his behalf.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.
