Quote by Charles F. Kettering (1876-1958)

• 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.

• 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.

• 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.

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