How to be Smarter: Work on becoming more ambidextrous (ability to use both left and right hands with equal skill). Start by brushing your teeth with your non-dominant hand every night. This gives your brain a workout by creating a new pathway for a daily task.
How to be Prettier: Use lip gloss to smooth brows back into shape when they become unruly.
How to be less Awkward: If you have to choose between standing awkwardly on the wall and dancing badly on the dance floor, go with the dancing. Nobody actually watches how you dance. Shuffle your feet, move your arms a bit, and try to look like you are having some level of fun.
