Most notable? Liam Payne wants to give up that nasty smoking habit and we're loving that he's ready to kick it to the curb.
At the KIIS FM Jingle Ball, the guys talked about what they want to accomplish in the new year, with Liam telling People.com: "I'm going to try and give up smoking, which is hard, but I do want to. I want to. It's about time. Need to grow up now."
To show their support, the hashtag #YouCanDoItLiam started trending on Twitter, with fans showing how much they believe in the 1D star.
As for Niall Horan, he's looking toward a healthy goal too, explaining: "I'm going to train, succeed in the gym this year. I always do it when I'm on tour and then when I get home, I'm crap. Yeah, I would like to succeed properly and get the job done."
And Harry Styles and Louis Tomlinson aren't quite ready to commit to any resolutions, with Harry saying it's "too early" to think about and Louis pretty much quitting before he even begins. We feel ya, Louis.
