5. Over Packing
Seriously, do. not. over. pack. When you're prepping for study abroad, you're going to be tempted to bring all your hair products, your 57 favorite shirts, and enough deodorant for six years, but resist! If you pack too much, you'll regret it - and not just because the Paris Metro system is a dark labyrinth of stairs and endless hallways or because you will have to haul your luggage onto a train and then shove it onto the tiny shelf above your seat. The truth is that you don't need as much as you think.
You don't need a year's supply of peanut butter - you'll forget all about it once you've had Nutella.
