Urban dictionary defines college as "a rite of passage into adulthood which involves rampant consumption of alcoholic beverages, flagrant and promiscuous sexual behavior, and a general and fundamental disregard for any form of responsibility by its habitants."

As a college student, you've had your fair share of experiences. Alongside your studies, you've had several realizations about life in general. Important ones to date: You can never own too many pens and eating pizza rolls without burning your mouth is near to impossible, so eat them anyway. Here's what was left out of the curriculum Pre-K to senior year.

1. "Learn to say no without explaining yourself" – Unknown

You're allowed to say no, so go with your gut. And get this: you don't have to feel guilty about it.

2. "The question of what you want to be when you grow up is one that you will eternally be answering" – Michelle Obama

Transitioning from kid to adult can be intimidating. You're making decisions that will impact the rest of your life, but just because you pick one major doesn't mean your future is set in stone. Other options will always be on the table, keep them there.

3. "The 5 by 5 rule: If it's not going to matter in 5 years, don't spend more than 5 minutes upset by it" – Unknown

In the moment, it can feel like your problems are literally ruining your life. Looking back on them now, you were probably being dramatic AF. Think of them as small roadblocks and don't let them hold you up for too long.

4. "Student is not a container you have to fill but a torch you have to light up"

– Albert Einstein

Being a student doesn't mean taking classes just to fill the credit requirements. Don't let your thinking become too rigid and remember what you put in is what you're going to get out.

5. "Great people do things before they're ready. They do things before they know they can do it. Doing what you're afraid of, getting out of your comfort zone, taking risks like that – that is what life is." – Amy Poehler

Venturing into new territory can open up doors you never knew existed. You can keep telling yourself you'll never watch the Harry Potter series, but what's the harm in trying? The only risk you're taking is the small chance of becoming addicted to Buzzfeed quizzes that tell you what house you'd be in.

6. "Give people high fives just for getting out of bed. Being a person is hard sometimes" – Kid President

Think about how everyone is going through their own set of problems. Wait the extra two seconds to hold the door open for the person behind you, and side note, smiling is contagious.
