I dunno--like any CEO or even VP or SVP-level executive, I'm sure he can afford executive assistants at work and nannies/assistants/drivers/servants at home to take care of all the normal mundane aspects of life that suck up so much of normal people's time, getting in the way of side projects.
I'd guess he has more free time than the random "3rd engineer from the left" on one of his company's projects.
