I almost joined too -- the Marines though. Took the ASFAB and everything, recruiter told me I could pretty much pick any field available to a non-com. Ultimately, the basic training scared me off. That recruiter was hounding me pretty good too, he thought he bagged him a grunt.
In retrospect, I should have joined. I think it would have given me the discipline that I sorely lacked as a young adult, discipline that took me a couple of decades to learn on my own with considerable turmoil through trial-and-error.
