How to be Prettier: Everyone must own flat brown equestian boots for winter. PiperLime.com has good options.
How to be (less) Awkward: An easy way to brag about your accomplishments at work without feeling like a show-off is to bring in food. Bring in a tray of treats, and send an email out to your group (make sure your boss is on the email): "I passed my Series 7 test! In celebration of this I brought in cupcakes. Happy Friday!" This lets people know of your accomplishments while also endearing yourself to them.
