Quote by Elmer Sperry

"The world rewards the stubborn. It doesn't reward the quitter."

"An inventor fails 99 times, and if he succeeds once, he's in. He treats his failures simply as practice shots."

"The real measure of success is not what you accomplish, but what you inspire others to accomplish."

"I have not failed. I've just found 10,000 ways that won't work."

"I've seen the worst humanity has to offer."

"Sometimes I wonder if the world is worth saving."

"Every choice shapes our destiny."

"Order is the foundation of a good life."
