Seriously, I implore you to do this and stop being rescue 911. I developed the awareness, unconsciously, back in middle school. I knew who the bad kids were, what I wanted to become, and what I was trying to avoid. I made those massive 'rite of passage' decisions throughout school and my brother didn't. I saw my brother smoke a cigarette at the age of 14 with a guy named Brandon...shortly after that, I promised myself that I would never inhale something that's not in Earth's atmosphere. It's hard to develop this type of awareness, but just know that if you don't, you will sink like your loser friends, too.
