Grey's Anatomy, Season 11

Amelia:
[opening voice over] In 1888, William Williams Keen became one of the first surgeons to successfully remove a brain tumor. A big win. It's true. You can look it up. What's harder to find, however, are stories of all the times old Double Billy K tried to pull a tumor out of a brain and lost. The losses must have happened. A surgeon must always be prepared to lose. And in neurosurgery, with the big tumors. We lose those battles as often as we succeed. The key, though, win or lose, is to never fail. And the only way to fail is not to fight. So you fight until you can't fight anymore. Hold up your head and enter the arena and face the enemy. Fight until you can't fight anymore. Never let go. Never give up. Never run. Never surrender. Fight the good fight. Even when it seems inevitable that you're about to go down swinging.
