The biggest inhibitor of creativity is fear of failure.  Often we don’t even let our creativity flow because we are scared of sounding foolish, or trying and failing.  When we suppress our creativity due to fear, our creativity goes away altogether.  Fear is a prerequisite to success.  To become successful at anything you must repeatedly fail at it at first.  Often failure is the best way to learn.  However we often want success without any failure which is kind of impossible.  So how are you going to let your creativity flow?
