People are very open-minded about new things - as long as they're exactly like the old ones.

One of the things we have to be thankful for is that we don't get as much government as we pay for.

We are just in the kindergarten of uncovering things; there is no downcurve in science.

Failures, repeated failures, are sign-posts on the road to achievement. The only time you don't want to fail is the last time you try something (and it works).

Do not bring me your successes; they weaken me. Bring me your problems; they strengthen me.

Thinking is one thing no one has ever been able to tax.

We must look forward to the future as that is where most of us will be spending the rest of our lives.
