The next verse is about how the man makes his transition into adulthood and suddenly finds himself dealing with the obligations of everyday adult life as stated in the lines "I've got so much more to think about/Deadlines and commitments/What to leave in and what to leave out." He also says "And the years rolled slowly past/And I found myself alone/Surrounded by strangers I thought were my friends/I found myself further and further from my home." These three lines refer to when he had the first realization that he was no longer the same person that he was years ago, or that he had lost himself which he says in the next few lines: "I found myself further and further from my home/And I guess I lost my way/There where oh so many roads." 'Home' refers to who he really is and the fact that he lost his way because of the "oh so many roads" is due to the confusion that comes from making the transition into adulthood when you're trying to figure out what to do with your life and I think that he's trying to say that he lost himself somwhere in all that confusion.
