Lust for the future, treasure the past.

You should always take the best from the past, leave the worst back there and go forward into the future.

In this bright future you can't forget your past.

Oh, yesterdays are over my shoulder, so I can't look back for too long. There's just too much to see waiting in front of me, and I know that I just can't go wrong.

I don't think the human mind can comprehend the past and the future. They are both just illusions that can manipulate you into thinking there's some kind of change.

I try not to look back. I'm looking forward. I'm worried more about what I'm going to do next week than I am what I did last week. There are too many things to do. Looking back is for everybody else.
