We are not bound to succeed, but we are bound to let whatever light we have shine.

Every once in a while a moment comes where you have a chance to vindicate all those best hopes that you had about yourself, about this country, where you have a chance to make good on those promises that you made… And this is the time to make true on that promise. We are not bound to win, but we are bound to be true. We are not bound to succeed, but we are bound to let whatever light we have shine.

President Obama
