Grey's Anatomy, Season 7

Meredith:
[voiceover] We are responsible with our patients. The problem is we blow it all out at work. In our own lives, we can't think things through. We don't make the sound choice. We did that all day at the hospital. When it comes to ourselves, we've got nothing left. And is it worth it—being responsible? Because if you take your vitamins and pay your taxes and never cut the line, the universe still gives you people to love and then lets them slip through your fingers like water, and then what have you got? Vitamins and nothing.
