Honestly, probably nothing. We are in the 21st century, the days of sacrifices are long behind us, but whatever, here are some things that will probably make you live longer if you give them up.

A fraternity or sorority house.

OK, I did this freshman year. I gave up one frat house that I used to go to all the time and, honestly, it sucked whenever they would have a party. But maybe you should do this if you have an ex in the frat, are becoming too much of a groupie, or (if you are at all like me) lose your phone (or a shoe) multiple times, and fall down the stairs too much. In my defense, those stairs are a safety hazard.

For those of you with less self control and will power you can always b.s. your way around it like my friend did, saying she was gonna give up one house -- on Thursdays -- because they don't have parties at that house on Thursdays. Genius. That's why we are friends.

Public hookups.

This will buy you some time avoiding the last psycho he hooked up with who is now obsessed with him. Avoid pda, live a little longer.

You will see how public opinion changes, maybe you will actually make some friends because you were not spending your Friday night sucking some rando's face. But, if this is too much, by all means you do you and keep providing your friends with more high quality snaps to post.

Boxed wine.

Generally, a good rule is to not buy any alcohol under $20 (if you are legal). See, you are not actually giving anything up here, you are just rewarding yourself by buying a nice bottle of wine. Treat yo'self!

Debit cards.

Try taking cash out with you everywhere you go for 40 days and watch how much money you save, and delete Venmo. Yeah, $6 mozzarella sticks do not seem so awesome when you only have $10 and still need a cab home. Doesn't mean you are making the right choice, but hey.

Brunch.

This is so anti-christ of me, but honestly, brunch is an ordeal and not one I have time for every Sunday. First off, trying to get all your friends up and ready is like herding cats and then by the time you are back, half your day is shot and you are not even in the mindset to work anymore.

Thursdays: it was the best of times, it was the worst of times.

This is also so not me. If you could find an advocate for Thursday nights, it would be me. For this we will need some basic math skills. Say you start pre-gaming at 9 p.m., get to the party by 11ish and end up back home by 1 a.m. -- that is only four hours of partying, all just to wake up at 8 a.m. (my schedule sucks).

Thursdays are a toss up, anyway; you have a 50/50 shot of actually having a great night. You know what I mean, Thursdays are weird.

Pop music.

If I hear another Megan Trainor song, my ears may start to bleed. Get yourself a Pandora, Spotify, 8tracks, Soundcloud, etc. account. Put it on a random playlist and listen to some music you would never think to put on. Listen to the music your parents listened to. You will seem much more educated when you can talk about music without bringing up Kesha. And, personally, you rank higher with me when I can have a conversation about good (aka RHCP) music with you.
