"Drifting into the abstract" is a NIN lyric, but "I'm just a pitiful anonymous" is a lyric from Marilyn Manson. I don't recognize the last part of that statement.
My chance to redeem myself, oldie that I am. Google is my friend. That last quote about dreaming is also a lyric connected to NIN members..the last line in "We fade away" by the band "How to destroy angels." What a sad song! But I love Jackson Browne's songs, so I can't talk.
The lyrics certainly fit someone who has lost his way in life.
