No matter what stage of life we are in, we can always benefit from the advice of others. As Meredith Grey once said,

"If there's just one piece of advice I can give you, it's this — when there's something you really want, fight for it. Don't give up. No matter how hopeless it seems. And when you've lost hope, ask yourself if 10 years from now, you're going to wish you gave it one more shot, because the best things in life, they don't come free."

Throughout the last 12 seasons of "Grey's Anatomy," we've loved, lost, laughed, cried and had our fair share of "dancing it out" with Meredith and Cristina. Even though "Grey's" has grown as a pop culture phenomenon over the years, I believe that the show is more than that, we have seen all of the characters grow from season to season, and we have learned a tremendous amount of life lessons along the way.

1. Never give up.

No matter how hard life gets, keep going at it. Think to yourself, "Will I regret not trying harder in 10 years?" Then realize that you just need to keep trying in order to succeed.

2. Don't feel like you aren't allowed to be upset every now and again.

I know this is kind of ironic coming from Meredith, but always leave room for yourself to be unhappy from time to time.

3. If you truly love someone, prove it.

Callie couldn't have said it better. You should never hurt the person you love or do something that will bring them down. Also, support your loved ones no matter what, because you know they are always there for you.

4. Find something you're passionate about and pursue it.

This lesson goes out to readers of all ages. Whether it's picking a major or career, to choosing to go back to school to change your career, you need to do something you love, no matter what sacrifices you have to make. Loving your occupation is one of the most important things.

As much as your significant other means to you, they should not be your primary focus. You do not need to revolve your entire life around them, I promise. You need to put yourself first sometimes, no matter how hard it can be. This is something I struggled with in the past, and putting yourself will both increase your happiness and make you more successful in the long run.

Quit planning every second of your life, only doing things because it looks good on your resume. Have some fun every once in a while. You need a break sometimes, and everything will work out in the end.
