Seems like a song of regret, wonderings of the past or what could have been. In my opinion:
The first verse is about not being afraid of standing out from the crowd at risk of looking like a fool. The second verse might be about the past being gone and some things being forever unknown. The third is about wasting time, not making the most of it and yet "not reforming" despite said wisdom. The fourth is about ignoring somebody, maybe a girl, not asking her out, and forever wondering if she felt the same. The overall tone of the song is to move on and avoid dwelling on the past.

One of my favorite hip lyrics among many others.
