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."

"Some battles are worth fighting."

"Sometimes you have to become the monster to stop the monsters."

"Skynet sent me back through time to kill you."

"War teaches us the value of peace."
