Dude, don't join the army because you feel like you failed at life. At least have a reason for it. A pride in yourself.
Do what you want. No matter the costs. This may be crazy, but the way I see it... as long as you're not hurting anyone but yourself: do what you want.
Be homeless. Do drugs all day. Be a prostitute. Fuck bitches get money. Get a job. Get a house. Raise a family. What ever.
Just do it. If joining the army is what you really want, then do it.
