How to be Smarter: If you can't figure out what you would like to do for a career, pretend you are introducing yourself at a party. Do you want to say "Hi, I'm Molly and I'm a teacher"? "Hi, I'm Molly and I'm a dentist?" or something else? Practice a few different ones; which one makes you feel most confident and excited? Be that one. How to be Prettier: Everyone always calls a sequined skirt a holiday basic, because, well, it is. This one is reasonably price and not super tight.
How to be (less) Awkward: Friends make you feel comfortable by letting you be yourself. People that make fun of you for not doing things you don't want to do, are not your friends. And there is a decent chance they were never your friends.
