If becoming a billionaire or not was simply a matter of choice for you I’m surprised you couldn’t figure out a way to do it without running through wives.
I’ve done in-depth studies of successful people since I was a young kid, and the richest ones simply didn’t seem to have time for family. You could probably crack that nut. I can’t. I have a house and a farm and a family close to me, however flawed. I’ll take it.
