How to be Smarter: You're old enough, at this point, to know without asking: your social security number; your parents' birthdays; and what kind of food to bring over when your BFF feels homesick. It's not that someone would mind telling you these things--it's that you know without asking that makes the remembering so powerful. How to be Prettier: An oval nail shape, not square, makes hands look longer.
How to be (less) Awkward: For the most part, respond to people in the manner in which they contact you. A missed call gets an call back, a text gets a texted repsonse. A twitter direct message shouldn't get an email, and a facebook message shouldn't get a phone call.
