We asked the editors and reporters at The Huffington Post to chime in on what they wish they knew when they were in college.
In no particular order, here's the advice we have to offer.
1. "Don't buy books from the on-campus bookstore! It's all a scam. Go to the neighborhood bookstore or order on Amazon.com."-- Dana Oliver, Fashion & Beauty Editor at HuffPost.
2. "There are SO many activities and events happening on campus. If you hear about something, go! Lego party at Tech House? Go! Fall dance concert? Go! Iran nuclear policy panel? Go! Obviously don't let it get in the way of schoolwork and healthy sleep, but you'll never be this close to so many incredible experiences. Say yes to them -- you never know what you'll find!"-- Erika Larose, Production Assistant at HuffPost Live.
3. "I wish I knew how developing bad eating habits in college would screw my metabolism up in the long run. So. Much. Pizza."-- Caitlyn Becker, Host/Producer at HuffPost Live.
4. "No one (including employers) cares how long it took you get your degree. Take the time to work on your resume before you graduate and make sure to take advantage of any career services your school offers -- having a well crafted resume is your best bet to getting that job/internship you want post-college."-- Shonitria Anthony, News Editor for HuffPost Voices.
5. Avoid Friday classes, and 8 a.m. classes, when possible. -- Multiple editors at HuffPost.
6. "The one year of statistics and computer science that I was forced to take was more useful then any liberal arts or social science prerequisite I ever took."-- Tiara Chiaramonte, Illustrator/Social media editor at HuffPost.
7. "Romantic relationships can be fun and important, but remember that this is also a time for you to grow as an individual -- don't accidentally isolate yourself in newfound love and forget to learn, both about and for yourself."-- April Saylor, Audience Development Strategist at HuffPost Partner Studio.
8. "No one is having as much fun as their Facebook profiles make it seem! Everyone is equally confused and scared and putting on a good front so no one from back home will think they're lame."-- Alana Horowitz, Senior News Editor at HuffPost.
9. "That college boyfriends are sometimes just for the learning experience and won't actually be anything more than 'that guy you used to binge-watch Game of Thrones and eat cheese withon Saturday nights.'"-- Jenna Amatulli, Associate Social Media Editor at HuffPost.
10. "Get a mentor. Whether it's an upperclassmen whom you admire or a real grown-up in the working world, having someone who isn't in the freshman bubble can provide really important perspective."-- Kim Bellware, Reporter at HuffPost.
11. "Alcohol doesn't have to be disgusting, but you are kind of setting yourself up for hating life when you take down shots of straight vodka. In other words, you are bound for awfulness if you think that 'vodka on the rocks' is a drink humans should consume."-- Rebecca Shapiro, Senior Lifestyle Editor at HuffPost.
12. "SLEEP. 8-9 hours. It's the most important think you can do. Figure out what time you need to be awake, then count back 9 hours and make sure you're away from everyone and quieting down. Do that for 4 days in a row and be amazed at your superhuman self. 98 percent of us need between 7-9 hours of sleep a night. If you think you only need 5, you're wrong. Go to sleep." -- Erika Larose, Production Assistant at HuffPost Live.
13. "One glass of water for each glass of alcohol will prevent hangovers. So will taking Ibuprofen before going to bed, but definitely don't take Acetaminophen because combining that with booze will be bad for your liver."-- Tyler Kingkade, Senior Editor/Reporter at HuffPost.
