How to be Smarter: Spend ten minutes a day doing something that will help you reach your ultimate goal. Ten minutes a day writing your novel; ten minutes a day doing jumping jacks; ten minutes a day researching better career options. Time adds up in a real, quantifiable way.
How to be Prettier: A lot of times what feels like hunger is really thirst. Have a glass of water, wait a few minutes, and then, if you are still hungry, eat.
How to be (less) Awkward: No coffee with espresso shots before job interviews. You will already be awake and pumped up enough--you don't want them to think you are a overactive, jumpy wierdo.
