"Dear Ten-Year-Old Self,

Before you ask me when you have your first kiss or if you'll ever have a boyfriend, I need to tell you some more important stuff first. What's more important than a first kiss, you ask? Plenty. First of all, don't let that kid in your class, Danny, who called you fat, make you self-consciously wear oversized sweatshirts for the next four years to hide your body. That kid is horrible and years from now he will be boring and bald and trying to get in touch with you to come to the set of the TV show you work on. No, you don't work on Cheers. That show's not on the air anymore. That would've been awesome, though. Another thing: Say thank you, always. Gratitude is the closest thing to beauty manifested in an emotion. When you're grateful, people are attracted to you. Also: Make sure you appreciate Mom and Dad. Yes, they never seem to let you do anything now except read books. Once you turn 18 you'll never get to live with them again, and you'll live far away, and you will miss them so much it hurts. Next: Learn forgiveness and bestow it generously. Finally: Don't let anyone give you any crap. Mastering a balance of these last two will take you a lifetime, so you had better get started now."

"Wear sunscreen every day."

"Dear Younger Self, 

Don't worry so much. Time will pass you by and what you'll remember are things like the smells of summer by the beach, a home-cooked meal, and the first time your child walks or says "mama." You'll forget that boy who isn't paying attention to you and you'll soon learn that being the prettiest girl in the room isn't important, but being the most fun, outgoing, bubbly, and interesting is.When times get tough, make laughing your priority. For years to come, it's the funny moments that you, your friends, and your family will talk about. 

Also, younger self:

• Never pay retail. The item will be on sale somewhere and getting a deal will make you feel better.

• Learn to drive stick when you first get your license or you may never learn.

• Tip everyone. It means much more to them than it does to you.

• Wear plenty of sunscreen, please. And do not be a sun worshipper.

• Have a family dog. Get one that is on the smaller side. They live longer.

• Always stop at lemonade stands.

• Wait for the good guy. Don't settle, but also know that there's no such thing as the perfect man. Marry someone who loves you no matter what you look like or say or do and who knows the real you.

• Read books. Read the newspaper. It instills confidence to be able to have a conversation at the dinner table.

• If you have a good idea, go for it. Don't assume it has already been done. Never assume anyone is smarter than you because they're not.

• Most importantly: Enjoy your life. Remember, you only get one."

"It's fine to make mistakes. In fact, embrace the mistakes because you move more freely when you have nothing to lose. "
