We're talking about Tina Fey and yes, she is seriously cool. Not only is she an entertainment industry powerhouse (she wrote, produced and starred in "30 Rock"), but she also created "Mean Girls" -- which means she knows a thing or two about what it's like to be a teen.
See below for the "SNL" veteran-author-wonder woman's best life lessons and when in doubt, just ask yourself: What would Liz Lemon do?
1. Don't be afraid to let it all out.
“Some people say, 'Never let them see you cry.' I say, if you’re so mad you could just cry, then cry. It terrifies everyone.” ["Bossypants"]
2. Sometimes, you're going to fail. And that's okay.
"Don't be too precious or attached to anything you write. Let things be malleable. For sketch writers, remember they're called sketches for a reason. They're not called oil paintings. Some of them are going to stink. You have to let them stink." [Esquire]
3. Always remember the cardinal rule of beauty.
“If you retain nothing else, always remember the most important rule of beauty, which is: who cares?” ["Bossypants"]
4. Stop wavering.
“You can’t be that kid standing at the top of the waterslide, overthinking it. You have to go down the chute.” ["Bossypants"]
5. Actions speak louder than words.
“Whatever the problem, be part of the solution. Don’t just sit around raising questions and pointing out obstacles.” ["Bossypants"]
6. Lying isn't worth it. Ever.
“’Cause living a lie will eat you up inside. Like that parasite I got from eating sushi on Amtrak.” [Liz Lemon, "30 Rock"]
7. Find people who share your sense of humor.
"I know for sure that you can tell how smart people are by what they laugh at." [Oprah]
8. Ignore the haters.
“Do your thing and don't care if they like it.” ["Bossypants"]
9. Be the smart girl at the party.
"I know having a boyfriend might seem like the only thing important to you right now, but you don't have to dumb yourself down in order for a guy to like you." [Mrs. Norbury, "Mean Girls"]
10. Trick yourself.
"Confidence is 10 percent hard work and 90 percent delusion." [Vogue]
