1. How to pull an all nighter.

Whether it's for writing a research paper or just staying up all night to talk to your roommates, there is a liberating feeling that comes with staying up all night. And let's be real, once you turn 21, all-nighters are a must!

2. Thank your family.

They've raised you for almost 21 years, so the least you can do is thank them for bringing you this far.....

3. Look back on your teenage years.

Welp. The next thing you really have to look forward to after turning 21 is turning 30, so just reflect on being young...for now.

4. Treat yo self.

Stop drinking that battery acid Burnett's and Smirnoff. Learn to stop buying the cheapest alcohol on the shelf, and try treating yourself to something nice every once in a while.

5. Take all the advice you can get.

Stop pretending like you've been 21 your whole life. Yeah, maybe your (fake) ID has said so, but let's be real, you're going to need more advice on your big night than you think.

6. Turn your phone off!!!!

It is not necessary to document everything you do on social media. You don’t need to put your whole life on display. Unplug yourself and have a little bit of fun.

7. Don't open a tab on your card

Hmmmm.....this one is a little tricky. Maybe you are feeling very spontaneous and want to buy drinks for everyone, but let's think realistically about your bank account. You will wake up regretting it.

8. Hangover cures.

Sparkling water, Advil, ramen, and a good nap work magic on hangovers. Don’t knock it ’til you try it.

9. Don't forget dinner.

Chipotle is always the answer to this one. Well, actually pizza is good too. Oh, and definitely nachos.

10. Don't take 21 shots.

After all, no one can drink like a 21-year-old better than someone who is under 21 (fact). You might rebound from hangovers easily and regularly pregame with 10 shots of cheap vodka.

11. Don't mix liquors...or do.

Friends will probably want to buy you drinks, but pick your poison and do your best to stick to it…and eventually switch over to beer.

12. Don't NOT dance.

Dance. Dance a lot. Dance like no one is watching and all those other cliche phrases. The best nights always involve dancing.

13. Don't die.

This should be pretty obvious, but it’s worth the reminder. Alternatively, don’t end up in the hospital or police station. Plenty of good stories don’t have endings in these places, so try to make yours one of them.

14. All of your parents’ friends will make jokes about how you experienced your first sip of alcohol on your 21st birthday. Every. Single. One.

15. All your friends will expect you to buy alcohol.

This will be fun and exciting the first couple times you are assigned this task. After that, it will just be one more errand for you to run when the novelty of brandishing your diver’s license wears off.

16. Real people drinks are great.

The "grown-ups" have been holding out on us all this time with their fancy cosmos and delicious exotic-flavored mojitos. No more red solo cups with cheap alcohol!! ...Or maybe?17. Did you know...
You are now legal enough to adopt a child...weird.

18. Get a stranger to buy you a drink.

Cuz why not?

19. You probably won't get any cake.

Rather, you'll get a shot with sprinkles and whip cream on it.

20. You'll probably have a week-long celebration.

You might want to start planning your aftermath detox right now...

And last but definitely not least....
