While it sounds like teenage rebellion on one level, it also sounds to me like someone not living up to the expectations of others. Do not stand in the shadow could mean don't live underneath other people's shadows, rise up above it and do what you were meant to do, or be who you were meant to be. He's saying no one freak out, no one try to stop it, it's okay.
At least the last few verses seem that way to me. The first few sound like I said, teenage rebellion.
