Here's the thing. He could be in a really good position now.
He seems smart.
He threw what sounds like a memorable party.
He has some publicity. I would say overall positive publicity as well.
He has a property.
He takes responsibility.
He could starting throwing parties as a business because if he's willing to take responsibility for what happened at his party, then he just needs to understand he can take that responsibility before hand and plan for security and medical and start something successful.
