Charles F. Kettering

Every great improvement has come after repeated failure. Virtually nothing comes out right the first time. Failures, repeated failures, are the posts on the road to achievement.

A problem well stated is a problem half solved.

The difference between intelligence and education is this: intelligence will make you a good living.

Our imagination is the only limit to what we can hope to have in the future.

Keep on going and the chances are you will stumble on something, perhaps when you are least expecting it. I have never heard of anyone stumbling on something sitting down.

My interest is in the future because I am going to spend the rest of my life there.

Where there is an open mind there will always be a frontier.

An inventor is simply a fellow who doesn't take his education too seriously.
