You have to be optimistic in order to continue to move forward.

We have to move forward,

As long as you lay down on the pavement, you will be walked on, spit on and play on.Stand up and be no one's fool.We all rode the fool's highway but find your exit

If you can't turn back the clock, you move forward.

You can't dwell in your past but move forward, look forward. That's it.

Everything must change, everything must move forward.
