How to be Smarter: If you are taking a class that grades participation or you are worried about seeming too quiet during office meetings, go speak to your teacher or boss frequently in private with questions that "came up after your meeting today". It will help your superior remember your face and hear your voice which will spark their memory when it comes time for grades or promotions, without having to participate during group meetings if thats not your forte.
How to be Prettier: Always put foundain on under your eye shadow so you don't get winkle eye lines.
How to be (less) Awkward: Loop everything back to the other person. A long story about your midterm should end with, "how many midterms do you have this week?" No one wants to hear only about you. Including you.
