Kettering, Charles F.

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

"You will never stub your toe standing still. The faster you go, the more chance there is of stubbing your toe, but the more chance you have of getting somewhere."

"An inventor fails 999 times, and if he succeeds once, he's in. He treats his failures simply as practice shots."

"The only difference between a problem and a solution is that people understand the solution."

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

"It's amazing what ordinary people can do if they set out without preconceived notions."
