I have my doubts that the people who write these kinds of posts truly did everything they say. As you say, it just does not seem possible to thoroughly work through all those math books + raising multiple kids + maintain friendships + working out daily (as he claimed he did) + work full time + things like cleaning and shopping and other chores.
He talks about spending ~10/week on math, with more dedicated when he was between gigs. If I replaced reading for pleasure and all television (not that I watch a ton, but maybe an hour a day or so), I could carve out 10 hours a week without making other changes.
