history: I'm trying to join the Air Force. It's exciting to think of the future, but it's also scary thinking of it. I don't know what to expect from Basic and I don't know if I want to give up 4 years of my life. Man_comma_ I know it's for the best_comma_ but I don't know if I'm ready to join the Air Force.
current: what is making you have second thoughts?
next: Well, I just don't know if I'm physically fit enough for Basic Training. And it's hard imagining signing a contract for 4 years. But, I know it'll be better in the end, it'll set me up with a good job and good work experience.
