Still I'm evolving and moving along
Cause looking back is just doing me harm,
I'm blocking that rearview
Evolving in the sense that he’s moving onto the next step and adapting to the climate & environment of the situation. He does not look back since it does him harm so he blocks his rearview. The rearview is a metaphor for whatever is in hindsight. He does not care for what’s past him or behind him, he just cares to move forward.
