If you watch "Grey's Anatomy," you're probably as obsessed as me. But what some people don't notice is that there are so many life lessons taught in the show. There are so many eye-opening quotes scattered throughout the show that i think we should bring to light.

1. "The thing people forget is how good it can feel when you finally set secrets free. Whether good or bad, at least they're out in the open, like it or not. And once your secrets are out in the open, you don't have to hide behind them anymore. The problem with secrets is even when you think you're in control, you're not."

- Meredith (Season 1)

2. "You just have to know. And when you don't know? No one can fault you for it. You do what you can, when you can, while you can. When you can't, you can't."

-Bailey (Season 2)

3. "Too often, the thing you want most is the one thing you can't have. Desire leaves us heartbroken, it wears us out. Desire can wreck your life. But as tough as wanting something can be. The people who suffer the most, are those who don't know what they want."

-Meredith (Season 3)

4. Some days ... the whole world seems upside down. And then somehow, and probably, and when you least expect it, the world rights itself again.

-Meredith (Season 4)

5. Reality. It's so much more interesting than living happily ever after.

-Meredith (Season 5)

6. Yes or no. In or out. Up or down. Live or die. Hero or coward. Fight or give in. I'll say it again to make sure you hear me. The human life is made up of choices. Live or die. That's the important choice. And it's not always in our hands.

-Derek (Season 6)

7. Just when we think we figured things out, the universe throws us a curve ball. So, we have to improvise. We find happiness in unexpected places. We find ourselves back to the things that matter the most. The universe is funny that way. Sometimes it just has a way of making sure we wind up exactly where we belong.

-Meredith (Season 7)

8. It's one of those things that people say, you can't move on until you let go of the past. Letting go is the easy part, it's the moving on that's painful. So, sometimes we fight it, try and keep things the same. Things can't stay the same though. At some point, you just have to let go. Move on. Because no matter how painful it is, it's the only way we grow.

-Meredith (Season 8)

9. They say death is hardest on the living. It's tough to actually say goodbye. Sometimes it's impossible. You never really stop feeling the loss. It's what makes things so bittersweet.

-Meredith (Season 9)

10. Sometimes the future changes quickly and completely, and we’re left with only the choice of what to do next. We can choose to be afraid of it, to stand there trembling not moving, assuming the worst that can happen or we step forward into the unknown and assume it will be brilliant.

-Cristina (Season 10)

11. Vulnerability isn't the opposite of strength. It's a necessary part. You have to force yourselves to open up, to expose ourselves, to offer everything we have and just pray that it's good enough. Otherwise, we'll never succeed.

-Meredith (Season 11)

12. Don't let fear keep you quiet. You have a voice, so use it. Speak up. Raise your hands. Shout your answers. Make yourself heard. Whatever it takes, just find your voice, and when you do, fill the damn silence.

-Meredith (Season 12)

These are just a few examples of the great life lessons "Grey's Anatomy" teaches you throughout the 12 seasons. I cant wait to see what season 13 brings!
