How to be Prettier: If you know you should drink more water but hate how boring water tastes, drink sparkling water instead.
How to be (less) Awkward: If everyone else is lip-singing along at a concert, but you don't know the words and do not want to stand there like your mouth is zippered shut, just mouth the word "watermelon" while bouncing your head in time to the beat. It looks like you know what you are doing then.
