Man, I know it's for the best, but I don't know if I'm ready to join the Air Force.
what is making you have second thoughts?
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.
there are other options in life but you must always follow your heart when making such important decisions.
