How to be Smarter: There is no point in going on a vacation you can't afford, or buying an outfit that doesn't fit your budget. You will be too unhappy with your financial choice to ever fully appreciate what you bought. How to be Prettier: The best subtle self-tanner I've come across. You can buy it at a drugstore, it doesn't smell horrible, and the color doesn't look fake because you build it up day by day.
How to be (less) Awkward: Don't title an email with "Sorry." Chances are whatever you are apologizing for--be it your phone dying when you were in the middle of the conversation, or for accidentally forgetting something important at work, the thread will continue after the apology has been offered and accepted. And then for the rest of the thread, going back and forth, when you see the email come into your inbox you (and the other person) will be reminded of the mistake.
