I don’t know a full answer but one possibility is:
What’s the easiest to replace?
Then you can sell that item and make it a point to replace it again in a year. You can even stash the sale money aside to buy it with the same money next year.

You can also go on a “focus fast”. Pick a category and go on a year fasting from it. The things you’re fasting from can go into tight storage or sold and replaced next year.
It will force focus on another hobby you have there.
