Advice: 4 or 6 year enlistment?

I don't care. I mean about all the drama. Join the AF for the minimum time that is offered for the field you wish to work in. That means four years. Four years will earn you the GI Bill and give you the feeling of accomplishing something. If you like it, you can re-enlist that much sooner. If you hate it, no big deal. You can gargle peanut butter for four years! Whatever you do, don't quit! And while you are in, make the most of what the AF offers. Get in some college so when you get out, your GI Bill will go that much farther. The FBI, if you still have that goal after four years, once an advanced degree. Good luck!

The military might actually solve your quitting problem as you definitely can't just quit. And they'll make damn sure of that. And also, judging what your career in the AF will be on how basic training is is really stupid, no offense. Basic training is to break you and build you up as part of a military so of course you won't like boot camp because it'll get very uncomfortable at times. Who's to say you won't love basic? The military puts you into a job that they know you'll thrive in otherwise LOTS of people will be switching rates and trying to get out. Just sign up and don't worry where your life goes. Who knows? You might make a career out of it.

Edit: Go for the 4 year enlistment. I'm sure if it's something that you've wanted to do for a while it's something you can manage. Also, you can always reenlist...

I would do four years. That way, you can get out after four in case you don't like it. I have seen people join up for 6 and hated it since they were stuck.
