It's not nearly consistent as 14 hours a day, 7 days a week. First, I don't sleep on a consistent schedule. Some nights I sleep 3 hours, sometimes 10. Usual is closer to 5. These hours of sleep may or may not actually occur at night. Second is that I'm not consulting, so "billable" and "work" aren't the same thing. Yesterday I spent: - 1 hour in a meeting with a potential customer - 2 hours traveling there and back on the subway, during which I read work-related research papers - 1.5 hours talking with my co-founder about stuff we've got coming up on the horizon - 1 hour reading and answering mails - 9 hours, from around 6:00 p.m. to 4:00 a.m., coding with a break in there for cooking dinner I then woke back up this morning at 7:30 a.m. and am about to get back to that code, after my morning routine of checking mail and news. :-)
