How to be Smarter: The worst emotion people can have towards you is to be neutral. People don't have to love you, but at least be interesting enough that they hate you. How to be Prettier: Dark jeans are almost always more slimming than light.
How to be (less) Awkward: If something embarrassing happens to you, make a joke. Even if its bad. A bad joke does more to ease awkward situations than being quiet. If you are too embarrassed to even joke, just smile an embarrassed yet amused grin at whoever saw you trip/stumble/knock over the yogurt display in the grocery store and move on.
