When DeGraw says, "I'm tired of looking 'round rooms /Wondering what I've got to do /Or who I'm supposed to be" he is saying that...
onstantly reinventing himself is exhausting, so he has decided to conform to the most commonly accepted standards
conforming is easier than being a unique individual
he is no longer willing to conform to meet the expectations of whomever he is with at any given time
he doesn't care if he has any friends or not
