It’s no secret that Princess Mia is still one of the most relatable movie characters of all time. Sure, she helped rule an entire kingdom at the age of 15 (NBD), but first she had to survive puberty just like the rest of us. "The Princess Diaries" movies have basically become a classic for our generation and will never get old. Here are some of the valuable life lessons we can all thank these movies for teaching us:

1. Friends are the people in your life who know your flaws and love you anyway.

2. Someone is always going to criticize you, but you just gotta keep moving along.

3. You're never late; everyone else is just early.

4. Sometimes the quickest way to a person's heart really is through their stomach (especially if it's pizza).

5. You are never too old to be silly and have a little fun.

6. You don’t need to be in a relationship to be important. You are incredible all on your own.

7. Others can't make you feel bad about yourself unless you let them.

8. We all have a little princess inside of us, no matter our age.
