I average 80 hrs/week currently; married with two kids. When I was married, no kids, I was working 92 hrs/wk on average (have it tracked), 50 at my main, 42 on the side.
I work three 16 hour days and three ~10 hour days (sometimes I take two days off and work another 16 hour day). One full day with my oldest child, and the other days I wake up very early and get home to do dinner and evening activities.
>>the majority of the population is not going to be to do this without slowly killing themselves.
We're talking about entrepreneurs, aren't we? People who want to make stuff? Yeah, they aren't the majority. I never said they were.
