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."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
