Stop trying to measure success by comparing yourself to everyone else.  Someones else's success can't be your's because their yes to God isn't yours.  Success will not always be your outcome you want in a situation but your success will always be YOUR YES to God in a situation.  No one can worship God like you or for you and if your life is an act of worship then your choice to to say yes to God when He calls is the simplicity of success in a world that is full of comparisons and contrasts.  Your trail of yes to God will look different than those around you but the blessing is guaranteed.  

"Your best" plus "God's bless" equals "your success."  So do your best with what you have with those around you with God's blessing.  Success is praising God despite the day or the outcome.  Success is blessing God despite how you feel or the mood of the room.  Success is honoring those around you whether they deserve it or not.  Success is moving past mistakes.  Success is forgiving an offense.  Success is rising above a disappointment.  Success is keeping joy from being stolen.  Success is fueling your fire to keep going when it's tough.  If you don't try you will miss out.  See...you're more successful than you think.
