For some reason my mind went to the scene in "City Slickers" between Curly (Jack Palance) and Mitch (Billy Crystal):
Curly: Do you know what the secret of life is?Don't ask me why. Sometimes my mind goes on a random tangent.
[holds up one finger]
Mitch: Your finger?
Curly: One thing. Just one thing. You stick to that and the rest don't mean shit.
Mitch: But, what is the "one thing?"
Curly: [smiles] That's what *you* have to find out.
