In my case I might be consolidating rather than shedding things. I decided a while back that I was only going to have one brand of striker pistol, and I probably didn't need a striker pistol chambered for something other than 9mm. I probably still have just as many pistols as I used to, but now they are variations of the same thing.
At the same time I am getting more aggressive about upgrading things I have intended to upgrade someday. Like I wanted a Dillon RL1100, and expected I would get one someday. Then it occurred to me that every year I waited was more than 5% of the time I would have to use the thing, so I sold some stuff I was never using and took the plunge.
I also always wanted the 10mm, but I never could decide it was worth the endeavor for a twenty grain gain in bullet weight. But that was back when I had a bunch of forty guns, and now I do not, soooooo maybe I might not be all that good at this consolidation thing...
