I know people tend to project a bit of themselves into their interpretations but here's my take:
The person the song is talking about used to be someone who never thought very much but also didn't fit in very well. The other person in the song was always very obedient and never broke any rules.
Now the first person is successful and has learned from their mistakes. The second person, however, hasn't since they never bothered to try anything risky.
