Underestimation

Don't get too cocky, my boy. No matter how good you are, don't ever let them see you coming. That's the gaffe, my friend. You gotta keep yourself small. Innocuous. Be the little guy. You know, the nerd, the leper, shit-kicking serfer. Look at me. Underestimated from day one. You'd never think I was a master of the universe, now would you?
– John Milton, The Devil's Advocate
