1. Cheaper is always better.
In high school you always had to have the new cool thing, in college you call it's a successful day if you score a deal on a shirt at Goodwill.
2. Staying out late is cool and all, but you'd rather go to bed at 8.
In high school you'd pull all-nighters over the weekend just to say you did, but in college all-nighters only happen during finals week because every other day we'd much rather go to bed around 8.
3. Studying actually happens.
You can't just breeze by with doing the homework because in college there really isn't homework, it's just studying. And studying is cool because jobs are cool and being financially stable is cool.
4. Eating alone becomes normal.
You used to eat with you squad at your specific lunch table, but in college you're just lucky if you have 5 minutes to yourself to eat in your dorm room alone before your next class.
5. Grocery Shopping.
When you lived at home you went grocery shopping if your mom forced you too, now you go because you actually have to provide for yourself and you need to find all the good deals. Also, I used to dread leftovers but now when I go home some weekends I pack up all the leftovers in the house and bring them back with me.
6. Judge-free zone.
You look at people trying new things or doing something different and you think that's one smart dude. Whether it be riding a razor scooter to class, wearing something you never thought was a possibility but it looks so dang comfortable, or even just having fun in a new way. No judgment here in college, we're all in this together. We're all sleep deprived, stressed, and hungry... that pretty much sums it up.
