I recently turned 21 years old. Despite having been an official adult for only a few days, I have already learned quite a few lessons about life and how it will be from here on out.

To help me explain the things I have discovered about adulthood, I have enlisted the help of some of my childhood heroes. Let's begin!

1. You will meet all sorts of people. You may like some of them, and you may not like some of them. Either way, these people will make your life well-rounded, which is what you need.

2. As cliche as this next one may sound, keeping a list is inevitable. As you grow older, you will find it difficult to keep track of all the things that need to be done. This is where checklists come in!

3. You're bound to have days when you feel like you just can't deal with it! Stress is a common emotion you feel as an adult, but the good thing is it doesn't last forever.

4. Tying back to the idea of checklists, you'll find that you're becoming much more organized as you enter adulthood. Whether it's a trip to the Bahamas or another day at the office, chances are that your bag will be filled with the essentials rather than the trivials.

5. Let's face it: all work and no play makes Jack a dull boy. Adulthood isn't all about hard work and deadlines, and cutting loose is the key to clearing your mind before getting back at it.

6. You'll feel a sense of accomplishment for completing even the most simplest of tasks. Getting your homework done? Great! Finished your laundry? Awesome! Got a raise? YEAH!!

7. Sometimes you'll find yourself trying to juggle everything at once. Multitasking is a skill that is learned through application.

8. Ah, commuting. Whether it's to work or school, you gotta do it at some point. Just make the most of it!

9. Your common sense will increase greatly as you enter the real world. To be more specific, you'll be able to tell the difference between someone who is genuine and someone who is superficial.

10. Now that you're an adult, guess what? You're in charge of your own decisions! Be it crazy or smart, it's all up to you.

11. Mornings might not be easy. That's where coffee/tea/smoothies come in!

12. When you're working with other people, they may suggest ideas that seem silly or meaningless. But give them a chance! You never know. Keep an open mind, always.

13. Yes, you'll finally be able to drink. Do it responsibly.

14. Be ready for anything, including saving the world.

15. When you move out on your own, you'll definitely have roommates. While you don't have to be best friends, make sure you get along!

16. Some days may feel like you're repeating yourself over and over again...

17. ...That's when you know it's time to shake things up!

18. Even though you're own your own now, remember to thank the people who helped you get to where you are today. Chances are you'll be needing them again!

19. And someday, you'll find that special someone who's exactly like you!

20. But they may end up driving you crazy. Might be time to keep looking.

21. That's okay because your needs come first. If you don't love yourself, how can you love somebody else?
