Being a grown up means going to work (or taking GOOD care of kids), showing up for things on time, thinking about others, not partying if you have other responsibilities, paying your own way, working hard at what you do, even if you hate it, being polite and respectful of others, and following at least 99% of the laws.
And as far as men go, the Airforce won't make you a man, only YOU can make yourself a man. My BIL is my age, but still lives at home, gets fed, etc. by his parents... he's not disabled or anything, he has a job, he just can't handle any responsibility besides mostly going to work... My DH, is as adult as he's ever going to get, at 35, but still is 12 inside... fart. hilarious.
