I get that there are parties going on every single night of the week when you're in college. If your friend passed the test she thought she was gonna bomb, party. If you survived a long day at work and got all your homework done in a timely manner? Party. Literally college students throw parties for everything. Don't get me wrong, they're fun to go to, but what's not fun is waking up the next day feeling like you've gotten hit by a bus. Who knows? You may have gotten hit by something; you might just not remember.
In my opinion as you get older, you realize that being 21+ and drinking isn't all that much fun. Yeah, the occasional "let's go to the bar, especially the bar that has karaoke on Friday nights because we need to sing our daily Spice Girls song," but thats about it. Though there are people who are all about drinking, especially on the weekends, because you finished another week in college. Wahoo! Let's celebrate. There's no problem with that, and there's also no problem having a get-together/girls night watching movies and making cookies. These chill nights can also include karaoke, so you're not really missing out. You can also include your ridiculous dance moves with your friends, so who is really having more fun here? Obviously the girls night.
It's important to know that it's OK to miss out on the HUGE party because you have a paper due on Monday and you haven't even started it. It's important to know that you don't have to have a get-together every weekend either. Sometimes you just need some time to yourself where you get in your zone and just relax. Whether getting in your zone is catching up on some sleep, which let's be real all college students could use, or even getting work done in advance so you don't have to stress yourself out next week when that paper is due. You've already got it done, it's submitted, so that Sunday night you get to sit back and relax, while other students are cramming (which is also fine, no offense to crammers and procrastinators because I'm one of them, but I'm learning that doing things in advance really does help you become less stressed.)
Live your college experience how you've always dreamed of, but know that again, if one night you're not really feeling like going out and your friends are like, "Oh come on, it'll be fun," it is OK to say no. Tell them to have fun and you can go about doing what you feel like doing. Studying? That's fine. Writing a paper? That's fine. Watching TV? Fine. Do what's best for you and just worry about yourself, relaxation time is the best time.
