I would now encourage you to go live a life without the regret that all you did was encourage others to believe like you did and understand the things you could comprehend. Instead be proud that you encouraged others to be smarter than you and wiser about decision and chose to avoid resolutions which only reflected the knowledge, experience and wisdom you possessed yesterday or decades before.
Find a way to grow, even when your old. (and I don't mean by gaining weight.) Find a way to accept others, even when your are confortable with yourself. Find a way to assist and be productive, even when you are retired. Find a way to avoid pride, even when you feel sure. Find a way to embrace humility, even when you are accomplished. If you find these things, then you just might avoid loosing yourself.
So go a few of the thoughts this speech inspired me to consider on this exciting Saturday morning. It's exciting because the world is still spinning, and the lungs are still working. Go enjoy it...
