How to be Smarter: Grown-up M.A.S.H. calculator. How to be Prettier: I own these shoes, in black suede, and get more compliments on them than any other pair of shoes I own. From the top, they look just like penny loafers, but because they are wedges they give the height of heels without the pain. (I wear them to and from work, without needing to switch into flats for the commute).
How to be (less) Awkward: If you have a comment or a question in a lecture, write it down before you raise your hand. It avoids the moment of panic when you finally get called on if case you have forgotten, and lets you begin speaking without starting with the "um" that can make you sound less confident.
