Getting to work by 6am usually means he drove without many cars on the road.
Way less traffic and that cuts my commute down by half. (1hour to 30 min)
And I found I actually like 2-3 hours of no distractions at the beginning of the day.
When I came in at 10am, it was 0-100 almost immediately because somebody always wanted something.
Took me a good month though to actually learn to go to sleep before 11pm. Originally whenever I slept before 11pm, even if I was dead tired, I would wake up at 2-3 am and not be able to sleep again.
