How to be Smarter: If you are making the choice whether or not to study abroad, go. Never again in your life will you have all that time off from school/work to go, the ability to have travel "count" towards something (your degree), a basically entirely scheduled trip at your disposal, and new friends/travel buddies (the other students) to go with. How to be Prettier: If you are sitting across from someone and they have something in their teeth but you don't know how to tell them, quietly ask them at the end of the meal if you have something in your teeth. Most likely, they will respond, "no, do I?" and then you have an opening to discreetly tell them.
How to be (less) Awkward: It's so sweet when you text your friends exactly at midnight on their birthdays, but for extra credit also text them at midnight at the end of their birthday, telling them you hope they had a great day and how excited you are for their new year, which starts now.
P.S. I was thrilled to do a Q&A with Andi from Polish My Crown, a great inspirational site that you will enjoy if you like SP&A.
