I am currently a Technical Sergeant in AFJROTC. I would say to succeed you just need to pay attention, be respectful, join a team (Drill team, Color Guard, etc.), and take a position of command, if possible. I am in drill team, logistics, CE, MWR, security, and I am a flight commander. Do as many community service opportunities as you can. Do not ask for a promotion. Stand out, take charge, and don't just blend in with the crowd. Basically there are plenty of opportunities to get yourself noticed by the SASI or ASI.
