If I was super rich like that, I wouldn't spend it on cars and yachts. I would spend it on coaches, tutors, trainers, personal chefs, training courses, seminars, gym equipment, stuff like that. Use the money improve myself, since that's the only true wealth there is anyway (that and relationships).
Others would say that would be a terrible waste of money that could be used to improve e.g. poor kids' lives. There's no such thing as true wealth, only opinions.
That's what I would do if I had billions of dollars. With millions of dollars, it's better to invest in myself so I can generate more wealth in the future.
The guy already had a personal chef. Which makes it even more silly. Probably used trainers, tutors, etc once in a while too and had a gym in his house he never used.
