Excuse my casual style of speech. Typically when seeking advice, I try to avoid specifics as I don't like the idea of "if you were me". To this end I typically will deliberately leave out specific details that could lead to specific advice, or requests for specific advice, from my speech/posts. Its just a personal quirk of mine, and I apologize if that mislead you.
I am currently taking classes for a field which I enjoy greatly, and would be a great career choice for me for a variety of reasons including likelihood for my success, good compensation, and personal enjoyment/fulfillment (IT security), which I already have some connections in. I have some experience in IT security already, however mostly through individual projects, either of my own or as part of a team.
So I would say that yes, it is more along the lines of "I have a great shot at an awesome career in a field I enjoy". The reason I am torn is more to do with the fact that all things related to security and warfare interest me, in both the physical and digital realms. I am utterly certain that what I want to do will involve at least some of the digital aspects of warfare and security (as these are the aspects I have some personal experience with, and can actually qualify my interest in pursuing a career in). As such, for a while (and still somewhat now), it really does come down to, at least in my mind, the myriad differences between the military and civilian worlds, as I can do digital/IT security in both. What else I can do on top of/beyond IT security is where some of those differences between the military and civilian worlds matter to me - what kinds of opportunities are available and how readily in each, for example.
Also, I am not offended about how much you read into my indecision (no way you could have known, as I didn't post details), but that was still quite a bit to try and pull out about my life. I will say this - yeah, the concept of throwing myself out into the world is in a way "scary", in that there are many, many unknowns. However I am totally fine with that, as I know I am smart and skilled enough to not just make a living, but make a career for myself in some field or another that I enjoy. It isn't that I am cocky or arrogant, I just am confident, due to successes on a variety of projects, that I have employable skills in things like IT security.
I hope this clears things up a bit about exactly what the source of my indecision is.
Yeah, you probably should have lead with the details. It's hard to give advice (maybe you weren't looking for advice, IDK) based off of what turns out to be vague details.
That being said, with what you want to go in to - I would look at MOS 35Q in the Army. You'll get the TS that is needed for all the good jobs in IT, and I think you'll be killing two birds with one stone as far as what you want to be doing with your life. You'll be able to say you served your country whilst setting yourself up for success in a field you enjoy.
