Then you'll have to ratchet up boundaries to address the relational patterns with people who are having a hard time, so that you're not a participant in their suffering.
And you'll have to start working on the patterns underneath the problems, which when you get into it starts to look more and more like the kind of megalomaniacal moonshot ("give computers arms and legs" / "fix the government now!") that the author ran out of gas on.
I think where you end up if you think about this is just recognizing that a) you probably should try to do some ambitious, high-leverage project to make the world better and b) reflecting about the world and about life in a thorough way is emotionally difficult for most people, so you also have to deal with those emotions.
The author's original somewhat manic intentions were probably right, and maybe he needed a bit more of a rest but was plowing forward out of fear that he'd lose his nerve. Now he's getting some rest and will probably figure out something big, important, and hard to work on in the next few years.
