Before you clock 30, you should know ...

1. How to fall in love without losing yourself.

2. How you feel about having kids.

3. How to quit a job, break up with a man/woman, and confront a friend without ruining the friendship.

4. When to try harder and when to walk away.

5. How to kiss in a way that communicates perfectly what you would and wouldn’t like to happen next.

6. The names of the secretary of state, president, powerful man of God, your great-grandparents, and the best tailor in town.

7. How to live alone, even if you don’t like to.

8. Where to go -- be it your best friend’s kitchen table or a yoga mat/eateries -- when your soul needs soothing.

9. That you can’t change the length of your legs, the width of your hips/Dic**k, or the nature of your parents.

11. What you would and wouldn’t do for money or love.

12. That nobody gets away with smoking, drinking, doing drugs, or not flossing for very long.
