I’m not going to do a 10x10 this year either. I am, however, going to help our regular gaming buddy finish his. It’s the least I could do after subjecting him to so many games of Brass this year 
Instead of a 10x10, I have a “play all my unplayed games” challenge on the go. That includes base games, expansions, unfulfilled Kickstarters, and preorders. I started it in mid November, and so far I’ve done 9 of 41.
Related to the above: play all of my unplayed games before buying any new ones. That one will have to start in the New Year, since I bought a game in the Boxing Day sales 
. That one might even be more achievable than normal, seeing as I doubt that our regular conventions in January and March will be on. For extra motivation I’m trying to save up money from my monthly ‘hobbies’ budget (created so that I don’t spend all of my disposable income on games, plants, and craft supplies) to buy a crokinole board.
Make some new local gaming friends. This one is very pandemic-dependent, obviously. We used to regularly be able to get 4-8 people together every week, but for various non-pandemic and pandemic-related reasons we’re down to 3.
