I think this song is about a man who has never allowed anyone to ever really love him. He's always pushed away typical happiness in every shape and form. Now he's become an old man living in his own world, alone. He's starting to really hit a point of self-actualization where life is soon coming to an end and he's finally looking back on what's been left behind. The worst part of it is that he knows he'll never change.

That's what I took away from it anyhow.
