I made it through Isaiah in Greek (and Hebrew) this year, thanks to the "Greek Isaiah in a Year" reading group. When I joined, the group was in its second year, and so there weren't very many of us who stuck it through to the end, but the list was discipline enough to keep me on track, and the experience was one of the highlights of 2014.
Russell Beatty has now started a spin-off "Greek Psalms in a Year" Facebook group, with a schedule (looks like 5-10 verses / day) that begins on January 1, 2015. For more information, check out the Facebook group or Abram K-J's blog (here and here).
It's a great opportunity to maintain and develop a biblical language*, and to spend time each day in the Psalms. Anyone care to join me?
* Don't be put off by the group name: As far as I am concerned, there is no need to read in Greek if you prefer Hebrew, Syriac or Latin (or some combination). Select your preferred ancient language, and follow along.
