Billionaires tend to be either completely crazy jerk like Trump, Jobs, Musk, Elison or terribly dull like Gates, Buffet or Zuckerberg...
Most do not drink any alcohol (they need their mind sharp at all time..), do not really party... Most will actually usually cut off their vacation because they get bored... Working and building stuff is what they like. Most are also really cheap actually.
Me I will never ever be a billionaire. No interest to focus so much of my life dedicated to work. I admire them but do not envy them at all. Heck they cannot even hire SP!
