Well I have my meeting Monday and as long as my test pass I'm joining and never looking back.
What do you mean pass your test? The ASVAB? News flash, you will likely "pass". The ASVAB is an aptitude test, nothing more. For some of the jobs, the score is relatively low, so your recruiter can always come in and say "Congrats, you passed! Sign here to become an 11B."
Find out what MOS you want to do. Find out the ASVAB score you need to qualify for that MOS, and then don't sign until you get that score. There are ASVAB improvement classes you can take if your score isn't high enough. Your recruiter might tell you to take a different MOS now, then once your in, you can take the ASVAB again and changes jobs. Don't do that. Yes, people can change their MOS once they are in the military, but they have to get approval from their command to let them go, and often have to extend their contract in order to do it. I've seen plenty of people want to change jobs, but they aren't allowed to since the unit is deploying for a year to Afghanistan and they're needed.
Besides the honor that you talked about earlier, what else are you looking to get out of it? You said you dropped out of college twice and you don't sound like you plan on going back. Major negative. College is one of (if not THE) biggest bonus the military gets. Not only do you get the Post 9-11 GI Bill, but while on active duty, you get extra money and can pretty much go to college part-time for free while working. Hell, to go full-time for free only requires an additional waiver for the money.
In the end, you're going to do what you want to. And that's fine, but I'm just trying to stress that you take a look at EVERYTHING before signing. If after you do that and you still want to sign, then more power to you.
What branch are you meeting with and what MOS do you want?
