One of the most beloved characters on "Grey's Anatomy" is Cristina Yang. Even though she is no longer on the show, she has taught us several different lessons. She has been relatable over the years and we wish she would come back to the show in the upcoming season. But, in the years that she was around she blessed the fan base with amazing knowledge.

1. She taught us that it's not always about how you look.

2. Sometimes we need to learn whether we are recognizing the problem or working through it.

3. Then, once you figure it out ... Cristina knows that you can get through whatever it is.

4. She taught us that even when we want to give up we shouldn't.

5. And when you keep on going; don't be mediocre. Always shoot for more.

6. She taught us that we need to work for what we have and that it is not always a walk in the park.

7. Then, there are some days that we still feel like this anyways.

8. Cristina Yang or college student?

9. Again, what we are all truly thinking as well.

10. She taught us that sometimes what we need is more important than making others happy.

11. Finally, that above all friendship is one of the most important things. We all need a person.
