I think this song is about wanting to live the life to the fullest and wanting a dream or ambition to believe in. And he doesn't know what he's waiting for, fear of being a nothing, nobody has taken over him and he's become it. The first verse is saying he's stranded around dull people and nothing is coming to save him. And the second verse is saying there's always something big happening but he keeps waiting, but what is he waiting for?
