How to be Smarter: A great read about making big changes in a manageable way. How to be Prettier: When you go to the mall, try on makeup samples at the beginning of your trip. The products that have held up best after shopping and enjoying a snack are then the ones you can go back and purchase at the end of the day.
How to be (less) Awkward: When surfing the internet, try to have the last story or video you read before heading to bed be something positive; I'm not sure if it is scientific, but I find that ending on a happy note make it easier to fall asleep. [Two of my favorite "happy things" to watch before bed are mentioned here and here].
