DSP is someone who never met enough resistance in his early life so he can't process it as an adult.
I remember someone contacting his highschool and confirming that he was, infact, a valedictorian. I doubt he put up a fake plaque on his wall for his fellow FGC butt-buddies or the teenager who lived with her mom with no intention of getting higher education or moving out, so that was probably a real acknowledgment. Point? DSP might be the "book smart" person that he hates, lack of self-awareness is one of his trademarks. Arguing against streaming with "Twitch is all subscriptions, subscriptions[...] gotta get those custom emotes and shit!" So if he's so smart, why can't he do shit on his own? Because he never did.
Phil mentioned his dad not being able to find a job for a while after getting laid off because they both "worked in the same sector". Let's assume that sector=company. Given how much Phil relies on his parents, it's really hard to try and not say that David got Phil the job. Phil could've performed well enough to be acknowledged, but there's no reason to believe that it was personal achievement, there's no way he was the head of the "Continuous Improvement" team. There was a obviously a reason that he got fired.
Youtube was the only thing that he made for himself, regardless of opinion Phil was a pioneer of the let's play genre. The thing is that no matter how much success Phil has, he can never keep it or grow it for a significant amount of time, probably because he doesn't know how "continuously develop" for shit.
He outright refuses to just fucking take the L. "The nook is full of shit that I can't sell at anywhere near the price that I bought it at? Whuuut? bugged resale mechanics, dood! I ain't sellin shit, then!" The CT condo was a fucking firetrap of wires, boxes, expensive plastic and unworn gamer t-shirts. He's an unstoppable hoarder who couldn't downsize unless he was physically forced to. If Marie Kondo came to the WAkahndo, there's a 77% chance that he'd ask for a positive contribution for everything that he tossed and call her a stupid gook bitch after she left.
He's more obsessed with image than he is reality. He went less than a year without a girlfriend before he poached some lady across from the country who seems to hate being around him because not having a girlfriend makes him see himself as a failure. He can't help whining about how hard he's working while also raving about how much he enjoys it because he need to be the hardworking breadwinner while also being a successful kahntent creator.
He doesn't listen to anyone telling him what he doesn't want to hear. The best example of this is Leanna literally telling him that he doesn't give her enough attention/fuck her enough, he still didn't listen because it would inconvenience him. For as much as he wants people to tell what they want from him, he won't listen if they say something that requires logic or effort.
Well, there's my tism for the month. This post really helped me get all the milk out.
