Fail

"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 at 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
