Stretch yourself a little and try something new. Go play in a new fandom or with a new pairing. Try working in a new medium. Or check out some fanworks that are new to you. (The recs from Day 2 might be a good place to start.) Leave a comment in this post saying you did it. Include a link to your post if you feel comfortable doing so.
Oh I am a bit behind - but that is one of the many things I love about this challenge. All the Mods start by reminding us that it is not a problem if we are late. I did an extra day at work, and it really knocked me out ... but am trying to catch up now.
Anyway - I tend to be very much "Yes, I love it, No I don't" sort of person. But, I have read a few fics of other pairings, and have bookmarked a few other fics to read. So that has been something I normally wouldn't do - a good challenge to start the year.
No, I haven't found another pairing to "ship", but I have enjoyed pushing myself to the challenge.
