If you're going to be in the military, there are a few truths (as I see them) that you should keep in mind.
First, do NOT join the military unless you very specifically want to do something that you can't get out in the civilian world. The downsides to military service outweigh the paycheck unless you're doing something you really enjoy.
Second, there is only one downside to being an officer vs. enlisted - you will never work straight office hours. Almost everything else, from personal freedoms as the new guy to the paycheck, is better as an officer. But the military does exact it's revenge, as a good officer typically shows up early, leaves late, works weekend, and gets left behind if he does only "his job". Enlisted troops have to get dirty and work 12 hour shifts like everyone else, but while a 2Lt with 1 week of experience may realistically get called upon to come in at 1am on a Sunday to bail a troop out of jail, the youngest enlisted troop that would typically get called to do that job would be a first sergeant with a dozen years of service. It's simply a division of duties and even if he's not on the ramp turning a wrench in a snowstorm, a maintenance officer (for example) isn't exactly keeping office hours either.
Third, in my opinion, leading is more fun than following. Yea being in charge can be scary and I've spent more nights awake worrying about the people who look to me for answers than I do worrying about what is important to me personally, but I still prefer that to having to shut up and take it.
Of course, if you just want to do your job and be able to go home without having to take your work home with you, maybe the enlisted force is the place for you. Everyone has to make this decision for themselves. That said, initiative and hard work is usually rewarded throughout the ranks, from the youngest airman to the oldest General.
Knowing what I know now, I'd do it again (USAF Academy) and I'm even more glad I didn't go enlisted because for me personally, the only possible job worth the daily military BS, stress, long days, early report times, and sleepless nights, is being a pilot. But that's just my opinion, and there are a few hundred thousand other troops who love the military and do not share my opinion on what is "worth it".
