"He doesn’t sleep. He doesn’t lose focus. He will even forget to eat. He executes again and again, inspiring those around him to have the same passion for the end game as he does."

I really wish we'd stop using sleep-deprivation and similar unhealthy patterns as a gauge for level-of-dedication. I'd hazard a guess that what makes Travis Kalanick so effective at what he does his willingness to do hard work, effectively choose between various risks and business strategies, and network well with other motivated people. The part where he doesn't eat probably isn't what's helping him.
