My 2015 New Years resolution was to floss every day. I have successfully done this so far, and plan to continue this practice for the rest of my life. As 2015 is winding down, I already have my 2016 resolution in mind.
Update, Dec 22 2015: Forgot what that resolution was, have a new one: Do 10 pushups every morning when I wake up before anything else. Every day.
Still flossing.
