We are not required to do anymore than OUR BEST.  Remember your best is not going to be the same everyday or every moment of your life.  Your best is not overdoing.  For those who do not know me, I tend to be an over achiever.  My son recently reminded me of this by saying “Just because you can, does not mean you should.”  We sometimes decide on how much to do based on, “well, I guess I can.”
