You do not have to be the best.  Just do your best.  Worrying about being the best puts you in competition and judgment, bringing on stress and striving.  At another level there is no other.  There is only Being.  Who are you competing with?  Do you see the folly?  Do what you do because it comes from Joy.  Do what you do to extend Love and success ensues naturally.  May that be a result, not the primary goal.  You cannot help but want to shine.  This is your true nature, beautiful Light, so shine, but do so simply for the sake of shining.  Peace.  It goes hand in hand with surrendering to Love.
