Maybe his kids are doing well because he has a lot of time to be a great dad and coach them?

Life happens. Shit happens. Kids happen. Enjoy the ride and don't terrify yourself about money or what your life should look like. We all get 24 hours a day on the planet and from a long term perspective, almost nothing of what we do really matters. Maybe by moving boxes instead of schlepping in a lab for some deranged sociopath like Elizabeth Holmes, the guy gets to spend a couple more priceless hours with his kids? The same kids that are going to be so far ahead because of his great mind that they will take care of him once they're adults and he has his time back once full-time parenting is over..

tldr: you sound very young so ponder this tip from a very wise zen teacher I had once "your life doesn't have to look like anything."
