Studying abroad changes you in ways that you could never imagine. By the time you go home you look, feel, and act differently, but you know it's in the best ways possible. You were able to taste amazing foods in their home countries (nothing will beat fresh stroopwafels from the Netherlands) and explore a new city basically every weekend.

1. You have a new outlook on life.

You might not have toured the world on a magic flying carpet, but you definitely know there's a lot more out there than you could have ever imagined.

2. Your Instagram will never be the same.

You became everyone's #travelinspo and you know that nothing you post will ever compare, so you'll just have to revive your feed with a travel #TBT every now and then.

3. You have a new craving for adventure.

It could be something simple like hiking a new trail or something extravagant like skydiving, but you always want to go on a new adventure.

4. You now have friends all over the world.

Whether you made friends with people who live in the countries you visited or with fellow travelers, the world just seems a little smaller and you can't wait to visit them all.

5. You have a new appreciation for different foods.

Whether you're a picky eater or not you were (hopefully) able to find at least one food in every country you enjoyed - even if it was just trying spaghetti in Italy instead of Olive Garden. You can probably even say that American versions of food aren't as good as they are in their home countries.

6. You've accidentally called US currency by another name (ex. euro, pound, franc etc.)

You've gotten so used to referring to money as pounds or euros etc. that switching back the dollar isn't as easy as it sounds. When you first got back US currency probably even looked and felt weird.

7. You're a pro when it comes to public transportation.

You've taken subways and trains and planes and buses and pretty much any other form of public transportation you could think of and managed to figure them all out - even when they were in foreign languages. At least in the US it's all in English so it takes half the time to figure them out.

8. A lot of your conversations are about your study abroad experience.

When you first got home from studying abroad it was all anyone would ask you about. It was a big part of your life for so long that it's kind of hard to just completely stop talking about it.

9. You've gotten used to not getting carded at a bar.

You got used to ordering a drink and having it simply handed to you no questions asked, but those days are over. Now that you're back in the US you're either pulling your ID out every time you order a drink or you simply never order one because you're underage again.

10. You've started to question the American lifestyle.

You've always considered Lucky Charms just another kid's breakfast cereal, but now that you've seen them in stores like http://www.kingdomofsweets.com you're starting to question whether it's just another breakfast food or actually a sugary snack.

11. You're always planning your next trip.

You've gotten so used to discovering new locations all the time that you can't imagine going back to your old routines and never exploring the world around you.

12. All of your #TBTs on Instagram are from your time abroad.

You might not be able to physically go back in time and relive every moment you had while abroad, but you took enough photos to do a #TBT every Thursday for the next few years.

13. You'd rather spend your money on traveling than anything else.

You could spend your money on material goods that you might get tired of after a while or you could spend it traveling the world and making memories that'll last you a lifetime. Study abroad alumni will probably choose the latter.

14. Time differences made it on your list of enemies.

There were times when you'd want to FaceTime someone, but the only way you could was to wake up earlier or stay awake later. And if your home university had registration scheduled at 10 PM EST that meant you'd have to register around 3 AM your time to get into all of your classes. It's safe to say you're glad to finally be back in your own time zone.

15. You've seen enough art to last you a lifetime.

If there was a free museum then it was most likely on your list of things to do in every city you went to. You loved seeing pieces like the Mona Lisa or the Statue of David, but at the same time you can only handle so much art before it starts to look similar.

16. You've become a lot better (or worse) at budgeting your money.

Best case scenario: you learned how to budget your money so you'd have enough to spend on traveling and souvenirs, but also enough to live on a day-today basis. Worst case scenario: you spent it all without thinking because you don't know when you'll have an opportunity like this again.

17. You didn't have to worry about the Open Container Law.

Photos of people drinking wine or champagne in front of landmarks in Europe and around the world are common and you finally understand why. Enjoying a bottle of wine in the park might have become one your favorite pastimes.

18. You've walked over ten miles in one day.

You know that walking is the best way to explore a new city because you get to see all of the touristy things, but also all of the little details that make every location beautiful. Some days you just walked until your legs felt like jelly, but it was so worth it.

19. You appreciate getting lost a little bit more.

You've learned that sometimes the best way to discover a new city is to just get lost and see what you can find. (And with things like GPS and maps you don't have to worry about getting too lost.)

20. You have a new found self-confidence.

Living on your own for months helped you learn how to take care of yourself. Any fears you used to have about becoming a full-fledged adult have lessened because now you know you got this!

If you get the chance to study abroad, you should definitely take it. Once you do, these will all be the symptoms of being a study abroad alumni!
