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."

"Friendship is built on trust and honesty."

"True friendship is worth more than gold."

"Good friends are like stars, always there even when you can't see them."

"Friendship means sacrifice."
