How to be Smarter: Your level of intelligence is not fixed. Today, research everything you hear that you don't know enough about to discuss with someone for five minutes.
How to be Prettier: When putting on perfume, don't rub your wrists together, it changes the scent of the top notes. Instead, pat them together.
How to be less Awkward: When talking to someone you feel is "better" or more "important" than you, don't panic or be timid. Remember that everyone, everyone, has had awkward dates, has screwed up at work, has stuttered during a presentation, and has had their heart broken. No one is immune to social pressures and feelings and disappointments, even the most important person in the world. Keeping this in mind is important.
