In vain have you acquired knowledge if you have not imparted it to others.
-- Deuteronomy Rabbah
Any person who recognizes this greatest power... the power to choose. Begins to realize that he is the one that is doing the choosing and that friends, although they mean well, cannot do his choosing for him, nor can his relatives. Consequently, he develops real self-confidence based upon his own ability, upon his own action, and upon his own initiative.
-- J. Martin Kohe
You don't get to control any outcome, only every choice you make along the way.
