Yes. The two main reasons I decided against the army were:
1. Somewhat of a pacifist so I find it hard to justify being part of such an organisation.
2. I want to experience life outside the confines of the army first. I want to do and enjoy things on my own terms. I would like to be able to drive my own car and come home to my own place and do what I want, rather than being at the mercy of the institution.
Take it from an old soldier, right now is not the time to join the armed forces.
As much as I loved being a Marine, it isn't for everyone and from what you have said so far, it would be far too restrictive an environment for you right now I think.
That is besides the inherent danger (as I can attest) currently due to our foreign policies.
