Charles F. Kettering

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

Whenever you look at a piece of work and you think the fellow was crazy, then you want to pay some attention to that. One of you is likely to be, and you had better find out which one it is. It makes an awful lot of difference.

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.

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.

A problem well stated is a problem half solved.

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.
