I'm assuming you have actually gone somewhere before and know how to travel. Meaning you have a passport, vaccinations, and realize that the U.S.A. is not the absolute best place on the planet.
Traveling is not hard. Just remember to be patient, and understand that figuring out the culture of the place you are going to is more imporant than understanding airmiles and how to redeem them.
I will give you a short packing list:
- Music (lots of whatever it is you like.)
- Books (I recommend buying an Amazon Kindle. Super convient, and you will save on shipping costs.)
- Games (personally I love video games and wish I would have brought more. Though keep in mind you may not have broadband internet wherever you are going.)
- Movies (Nothing like a good mindless zombie movie to help you unwind on the mission field.)
