Grey's Anatomy, Season 11

Meredith:
[ending voice over] Surgeons are bred to be invulnerable. It's very hard to lay ourselves bare, because we know exactly how deep some injuries can go. But vulnerability isn't the opposite of strength. It's a necessary part. We have to force ourselves to open up, to expose ourselves. To offer up everything we have and just pray that it's good enough. Otherwise, we'll never succeed.
