I definitely agree that trying to prove himself and show that he is trustworthy to those who hate him is definitely a factor along with the fact that he has so much he wants to do and probably feels like if he slows down he won't ever get the chance to get everything done. He is definitely a people pleaser and would rather put others before himself.if he has commitments he isn't going to willingly cancel, he's stubborn to a fault and sm definitely enables it
