In order to succeed you must fail so that you know what not to do the next time.

People who fail in achieving a goal of theirs should do what little children do when they first get burnt, fall, or get hurt, that is learn a lesson. So next time you face the same exact problem, you know what to do or not. Once you’ve overcome all the obstacles that would stumble you, you’re on your way to success. The second shot kills the target.
