I have stopped buying and now only do trades. There are things that I use all the time, there are things that I use occasionally, and then there is stuff that's in my "churn pot". The idea is to replace the churn with things I will use. It's a very slow process as shiny objects tend to trick me into thinking that I might need them while I really don't and won't, but it still works.
I dread the moment when I realize that there is nothing left to trade, though I am hopeful that my ability to recognize my true needs is just bad enough that this horrible moment won't come soon.
