You collapse a few times, and you put your head in your hands, and you say, "Oh my god, how am I gonna get through this?" You have a few of those nights, and then you get over it and you keep it moving. And those nights... As you get more used to the strain, I guess those nights are fewer and farther between. So that's the best you can hope for. It's a tough job and it's a lot to pull out of your brain.
