Divorced man that has lost touch with society, that's a mixture known to cause depression.
You really think a 36 years old billionaire ex-married man wouldn't have done hobbies already? (and much, MUCH more) Why is it so hard for you to understand that not everyone is the same? He has issues, is not about being a "hard" thing to do. The guy's a billionaire, he probably has done more than most of us will do in our entire life. I'm not defending him by the way, I'm pointing out that he has issues, which is obvious.
