Tell "everyone" to go back to hippieland.

If you really want to be in the military, go for it, it can't hurt you, and nobody is going to force you to re-up if you find it's not for you.
That being said, no one can make the decision for you, and it's hard to even advise someone on what you think is best for them without knowing them and their options pretty well.
But good luck with whatever you decide, if you get any specific questions, we have all kinds of experience here to help you out.
