With regards to tactics and ChessTempo, my 2013 goal was to do 20 problems (blitz mode) per day. At 365 days in a year, that works out to 7300 problems. I did 7560 problems. Granted I was scrambling to get a few more in on January 1st and 2nd, but it wasn't a marathon session.
Compared to 2012, my overall accuracy improved. My average monthly accuracy average in 2012 was 77.55%; while my 2013 average monthly accuracy was 81.89%. The highlight of the year in the accuracy category was hitting 85.00% correct in October (578 correct out of 680 attempted). My overall accuracy percentage began 2013 at 72.15% and I finished the year with 74.43%
As far as ratings go - it's always up and down. I try to look at the trends; and the trends say my rating is steadily declining. For example, in 2012, I hit a max rating of 1752.6 and my highest monthly median rating was 1721.9. In 2013, the highest I could hit was around 1748, while the best monthly median was only 1710. 2013 also saw me hitting a new low in blitz rating at 1633 (1637 was the lowest I hit in 2012). In December, my max was only 1699 with the median at 1679.
So, in summary, it looks like I'm taking a bit more time (improvement in accuracy), at the expense of my rating.
For 2014 - my goal is to attempt 7600 problems; keep improving my accuracy, but also see if I can stem the decline in ratings.
