"You get what you get, and you don't get upset" -- Unknown

How to be Smarter: Don't use the phrase "I believe." Its redundant. If its coming out of your mouth, everyone's brains automatically default to knowing that's what you believe. 

How to be Prettier: Everyone has a little black dress; get yourself a little white dress. I like this one a lot: http://www.forever21.com/product.asp?catalog%5Fname=FOREVER21&category%5Fname=dress%5Fdressy&product%5Fid=2060482950&Page=1. I'd wear it with gold flats and a long gold necklace, or with black flats and pearls. 
How to be (less) Awkward: There is always a debate for taking the stairs versus taking the escalator. The easiest way to settle this is to walk up the escalator while it is moving; this combines the best of both worlds.
