No way, man. You still have this completely backwards. Everything he's doing is for the sake of avoiding conventional responsibilities. You should not mistake his pigheadedness and entitlement and delusions of grandeur for "drive."This guy definitely has some kind of drive. Shit, how many people would travel across the country like he's doing?
He started this trip because he was basically out of options, not because he was driven by a grand vision. He has been continuously failing because of his arrogance and laziness, not because of the difficulty of his goals.
He has no money and he has no willpower for dieting. A responsible, driven person in his shoes would be taking the initiative to learn how to diet properly while seeking/maintaining conventional employment. He's convinced he doesn't need to do any of that.
He can't cope with the fact that for most people, employment and physical fitness are not some glamorous things that net you a bunch of attention and adoration.
Leading an adult life is an unpleasant grind that requires focus and maturity. He can't handle any of that, so he's chasing a harebrained dream instead.
You could argue that he's driven to get attention, but he's even lazy about that. All of his efforts to organize this "journey" are obscenely half-assed, and he constantly whines about how the logistics of it all are so difficult.
All of his "drive" stems from his persistent delusions about finding an easy way out.
