Gunpla. Save for the excellent MG ver.2.0 Zaku II(-S), many of the Master Grade models this year were disappointments. The new Gundam 00 lineup looks very, very promising though.
Relationships. Regulars on this blog already know why. I promise I'll relish being single. Women have no idea who they're overlooking. Their loss, not mine.
Vices. I don't want to get into too much detail, but this year I lived pretty dangerously, thinking with bodily appendages that aren't anywhere near my brain. This has to stop.
Health. My resistance to sickness tanked after the toll of OMR17 in October and November. Chalk that up to insomnia and overfatigue.
