“It’s hard to be humble when you’re as great as I am,” Muhammad Ali once said. Yeah, okay. That’s why great people have to work even harder to fight against this headwind. It’s hard to be self-absorbed and convinced of your own greatness inside the solitude and quiet of a sensory deprivation tank. It’s hard to be anything but humble walking alone along a beach late at night with an endless black ocean crashing loudly against the ground next to you.
