10 New Year's Eve Secrets We Wish We'd Known In Our 20s

New Year's can be a super-stressful time. The possibilities are seemingly endless — one friend suggests renting a table in the club and getting bottle service all night, your S.O. wants to stay in and watch The Nightmare Before Christmas ironically, and Justin Bieber just DM-ed you on Instagram to see if you'd wanna hit up Ibiza and chill.
