"There's a whole bunch of things I don't know a thing about — I just stay away from those. So, I stay within what I call my circle of competence."

“Those who attended last year saw your Chairman pitch to Ernie Banks. This encounter proved to be the titanic duel that the sports world had long awaited.

Thus, for every Inevitable, there are dozens of Impostors, companies now riding high but vulnerable to competitive attacks.”
