Figure out what you will be doing, where you will be going, for how long etc.
Figure out if the money you get for going to those places and doing those things there will be worth it. Talk you your parents get their opinion, and talk to your girlfriend to see if she can handle not seeing you for long periods of time.
That's a great idea. Thanks man. I really appreciate it.
I do want to join but I'm hesitant at the same time due to family and friends, but it also something I would like to pursue for life experience. Maybe I should hold off? I have no idea...
