I think his status as a single child-free person goes understated in this article. It takes a special kind of husband&#x2F;wife to be okay with someone who works this hard and not having to juggle a home life frees up his schedule to a huge degree. I can imagine working hard 18hr days while still in my 30s, but I cannot imagine doing that while maintaining a marriage and taking care of a kid or two. The guy is a billionaire so I guess he could pay for full time staff to help out but that isn&#x27;t really the same as being there in person.
