How to be Smarter: Before you leave your desk for the day, lay out what you will need for your first task tomorrow: the files, textbooks, or supplies you will use to tackle the project. Having the items laid out already when you begin working again will both remind you what you prioritized as the first task of the day yesterday, and make it easier to start right in without spending the first few minutes of the day hunting around for a missing folder or set of notecards. How to be Prettier: How to make flossing a habit.
How to be (less) Awkward: When you are en route and letting someone know when you will arrive, instead of giving a time estimate ("ten minutes away") which could fluctuate based on traffic or wrong estimation, give your location. "Six blocks away" or "On 14th and 3rd" gives the person a good idea of how close you are without them basing their schedule on a time estimation that could be slightly off.
