12. If At First You Don't Succeed, Re-examine If It Was The Right Thing To Do.

The definition of insanity, is apparently to repeat the same actions and expect different consiquences. So in my experience it's best to look into why whatever it was that failed, failed. 

Is it something you really want to do? Is it worth trying again? If you try it again what will you have to do differently? And how will you do it?
