I wonder if there was anything in particular that set off yesterday's temper tantrum? He seemed very fixated on the money he got for his birthday stream not making a difference, so did he see the detractor restream, did one of his whales tell him they were burned out, Khet wanted money spent on her, or simply that he feels entitled to $300+ a day on top of his "marathon"?
1) A lot of it starts with his narcissism and ego. He feels he is owed this money every day. It was never their money. Its HIS. He entertains them so they need to reward him. He truly thinks he is the hardest working guy on the planet.
It's the same reason he goes on spending sprees even when he knows he shouldn't. One tiny part of his brain says "i shouldnt spend this on mobile games - i cant afford it" while another says "do it!- you deserve this!!! You can make up for it tomorrow. You work too hard not to have this."
He really thinks he deserves to have anything he wants because he is DSP with a 13 year legacy who works harder than anyone.
2) The anger is totally addiction behavior. let's be honest. He is an addict that wants to keep getting mobile game fix while living his "life of luxury"
He doesn't know how to budget. The bank leaks revealed that, even post bankruptcy, he would still overdraft. He would have itunes transactions the day before his mortgage was due. He hasn't learned anything. He even admitted he loses money from the PayPal fees of instantly transferring the funds. The man could be saving a ton a year just by waiting the 3 days.
*side note* my opinion is that he didn't realize it was his anniversary and the next day was his day off and he wanted to do something special for khet but without the funds needed to guilt trip his audience into giving more than usual.
Anyway- the anger stems from his ego thinking he deserves that money and since he doesn't have it it's frustrating. Secondly he is angry because he feels like his whales are holding out on him.
I wasn't a psychology major but I once read that anger is a second emotion that stems from a first emotion and in Phil's case that first emotion is sadness.
He is sad that he is a failure at life. He is sad he has a sham marriage. He is sad he looks like shit. He is sad he can't pay his bills and had to file for bankruptcy. He is sad that he has no friends. This is easily provable by the way he talks about it and how hard he tries to cope with it.
He is so immature that he doesn't know how to process that sadness and leverage that energy to improve his situation so he turns to anger and lashes out at his viewers.
3) The other 2 I feel strongly about...this one would be a stretch. But maybe turning 40 and being a failure is finally hitting him.
Anyways- just my two pennies. I'm open to other theories.
