Age means nothing. Dont go in there thinking they were waiting for you to come save the day for them, and lead the flight. My flight went through a couple guys before they got bored of making examples of them, and settled on the last guy. Its all head games.
They overload your mind with 200 things and if you remember 150 of them, they want to see how you react about forgetting the other 50, and also how you respond to them jumpin all in your toejame.
Dont get assigned laundry detail. Cleaning the toilets is better. Hand picking through 12 or so fellow airmen's dirty underwear is not pleasant. I know.
Go into basic with the goal of getting through it. If you listen, and pay attention, show you have qualities of leadership, you will be noticed. Just dont go overboard trying to get noticed. They know.
After that, do well in the school they send you to, and good luck in a duty assignment. Save your money!
