And before some kid comes on here telling me which circle of hell I'm from:
Every single military female that has done the things that I've mentioned started out with the exact same statement that I quoted you using above. And to prove that I'm not a pig, military men try to use a power play of the same order: by screwing over everyone that they can possibly come in contact with, in order to achieve their own personal goals. I've fallen into the same trap myself, as have everyone else that's been in for at least a week.
The military's not about getting what YOU want. They give you all of those perks so that you can GIVE BACK. You're not getting loan repayment, etc, just because you're a great and wonderful person. It's because the soldiers need health care. If the soldiers go somewhere, then you will go there to help them. If you don't understand that, then you're gonna treat the person in your chair like a dog simply because they have on a uniform that you disrespect. THAT will be the experience that you learn. THIS is why military doctors and dentists get the bad rap that everyone's heard about.
So, before you sign anything, consider if you can keep your commitments in the face of people breezing by and screwing you over just because they think they're special (for the next large chunk of your life) and not become some angry jerk like me. Consider whether you can resist jerking some poor guy's jaw around just because you're mad at your commanding officer's choice of words on a report that your life depends on, just because the poor guy's an E-2. If you are thinking that your life is going to be taken away from you, then you're exactly correct. It's not about YOUR life, it's how you can USE your life to help other people and still feel like you're happy. This is exactly the problem when you so woefully proclaim that you don't want "to be deployed at a moment's notice". Saying such a thing is already disrespecting a life that you're considering being a part of.
This isn't me attacking you because of my opinion of the war or for any other reason, this is an opinion from someone who spent nearly a decade in the military and can attest to the things I've mentioned. Do you believe you can give the best care in the face of having your self-importance taken from you? Do you believe that doing so will make you an incredibly wonderful practitioner, or even understand how? Or are you scared by someone with a strong opinion, and wouldn't be able to clear your head to practice dentistry at your very best? Or are you too worried about leaving your current post because of your nice oak cabinets and easy commute?
This isn't me being mean or trying to scare you away. I'm just giving you a heads-up. You can spend your time in the military trying to run away from the dirty jobs, and screwing your peers over by doing so (as you seem to be doing already). Playing the system will basically cause you to worry the entire time, though, besides turning you into human garbage and screwing up your morality. Go read about the amalgam-caravan and the people who spend 4 years trying to avoid it, scrutinizing over every career decision. Then, realize that's why it exists in the first place. Then, ask yourself if you're ready to work next to jerks like me.
