"Would you like me to give you a formula for success? It's quite simple, really. Double your rate of failure. You are thinking of failure as the enemy of success. But it isn't as all. You can be discouraged by failure - or you can learn from it. So go ahead and make mistakes. Make all you can. Because, remember, that's where you will find success."
Thomas J. Watson

"While one person hesitates because he feels inferior, the other is busy making mistakes and becoming superior."
Henry C. Link

"Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep."
Scott Adams (1957 - ), 'The Dilbert Principle'

"There are two mistakes one can make along the road to truth...not going all the way, and not starting."
Buddha (Hindu Prince Gautama Siddharta, the founder of Buddhism, 563-483 B.C.)
