"more"
Shia's character asks Brolin's what his "number" is, the amount he'll make that'll get him out of the game entirely.
Brolin says, "more."
Someone on the "Scarface" board just asked why Montana didn't quit earlier and retire. I've been thinking about how a lot of us ask ourselves questions like that, which is why we typically don't build those kinds of fortunes.
I suspect, very strongly, that none of them are doing it just for the money. The process is what they love; the money is just how they keep score.
Embarrassingly, it was Dr. Phil who reminded me of this - in a podcast, he admitted he got into the TV business with an eye towards retirement once he got his "fuck you" money (his words, not mine), say enough for a private jet. He passed that number a long time ago, and now admits he does it because he loves the work, such as it is.
