They say that with age comes wisdom. Maybe. Maybe not.

1. Life is too short for you not to be happy.

So do what makes you happy. Start today.

2. Tomorrow is not guaranteed.

So tell everyone you love them as much as you can today.

3. At the end of the day, your family is most important.

And you should call them every day; they're your biggest support system.

4. Eat the pizza.

Because, why not? You deserve it.

5. Take way too many pictures.

They never change, even when the people in them do.

6. Mom was right about the girl.

You probably shouldn't have trusted her.

7. And dad was right about the boy.

You really shouldn't have trusted him.

8. Sometimes, you need to lay in bed and watch Netflix.

One Tree Hill? I think yes.

9. Not everyone in your life is meant to stay.

So don't be upset when they leave. One door closes so that a better one can open.

10. Loving and respecting yourself is so important.

If you don't love and respect yourself, it will be hard to find someone else who will.

11. Not everything will go as planned.

But that's okay. Some nights are better when they don't go the way you want them to.

12. You're more than your GPA and your test scores.

You're you. One bad test or one bad semester will not kill you.

13. It's more than okay to cry.

You don't need to pretend that you're okay when you aren't.

14. It's also more than okay to make mistakes sometimes.

You live and you learn; keep growing from your mistakes.

15. If he breaks your heart, he wasn't worth it.

God has someone much better in store for you-- just wait.

16. The past is the past.

If you dwell on it, you will never be able to move on and see all of the beautiful things ahead of you.

17. You don't EVER have to give in.

Say no. Say you don't want to go to the party. Say you don't want to hang out with him.

18. If you want to be with him, be with him.

Learn how to do things for you. Do what makes you happy.

19. It's always going to be okay at the end of the day.

Never forget that God wouldn't give you anything that you couldn't handle.
