"Optimism is really rooted in gratitude," he says. "Optimism is sustainable when you keep coming back to gratitude, and what follows from that is acceptance. Accepting that this thing has happened, and you accept it for what it is. It doesn't mean that you can't endeavor to change. It doesn't mean you have to accept it as a punishment or a penance, but just put it in its proper place. Then see how much the rest of your life you have to thrive in, and then you can move on."; — MICHAEL J. FOX
