How to be Smarter: "Everything I’ve ever learned about everything (in less than 300 words)." Love all of these phrases. How to be Prettier: This is so helpful: how to make better-looking slides.
How to be (less) Awkward: If you already know in your heart you're going to say no to something - whether it's a new job offer, a brunch invitation, or a date, let the other person know as soon as you can. Saying "maybe" or drawing out the no usually just makes the eventual "no" more inconvenient/painful for the other person.
