A scene from an episode of Mad Men is stuck in my craw:
Hilton: I think you know I'm in a bit of a crisis tonight.
Draper: I didn't know that.
Hilton: I think about my business day and night. And I'm a harsh critic, especially of myself. And sometimes it collects, and I feel bad. And then I realize maybe that's the reason I'm so lonesome.
Draper: You might be working too much.
Hilton: I'm not working enough.
