How to be Smarter: Dry your hands completely after washing them. The extra water can dry out your hands even more after it evaporates, and damp hands spread 1,000 times more germs than dry hands (source). How to be Prettier: An occasional dress-down outfit during a night out will turn some heads. You stand out when you catch people by surprise.
How to be (less) Awkward: If you are having guests over, make sure to have enough chairs for all. Nothing makes a guest feel unwelcome faster than having to count chairs and realizing they are one short just before the meal.
