Working 24 hours a day isn't enough anymore. You have to be willing to sacrifice everything to be successful, including your personal life, your family life, maybe more. If people think it's any less, they're wrong, and they will fail.

I have friends of mine that are actors or singers, and they're the classic guys where, they're onstage, and they're like, 'Okay, the blonde in the third row, seat 24, bring her to my dressing room.' I've never, never taken advantage of that, I swear to God.
