>> The average tech CEO does not work 11.5 hours a day, 7 days a week, 52 weeks a year. There might be a few tech CEOs who work that long, but I am guessing for most of them it isn't a sustainable workload.

Articles often get to this by counting stuff that you and I would consider not-work time. I read an article about a banking CEO who claimed to work 65+ hours per week. His daily schedule went from 6:00 am to 7:00 pm each weekday. That included taking calls as he commutes for an hour, a breakfast meeting, an hour at the gym with a couple VP's, and an hour networking at lunch. His actual desk-and-meeting time was about 9 hours.

It's still a large time commitment, but it's not that different from what the rest of us do.
