Heya,
I'm always enjoying trying a new camera body or lens, I do a simple system where I get it and then sell/trade things to make up for it, so I'm always rotating things. I have staple gear that I keep, and then there's the other stuff I try, keep, sell, trade, etc, so that I can have fun and try things, but not end up keeping everything. I had 7 bodies not long ago and (as you know) reduced down that count, then promptly it filled again. I recently traded out glass too. I just use the gear until I figure out if it's something I like or if it shows me I want something different and just keep swapping it out. That way I'm not spending tons of money and acclimating stuff like a collector and just have a constant shuffling working group of cameras & lenses. I just like to try things out. Sometimes I'm in the mood for something nicer, sometimes I want something old and hard to use, etc.
Very best,
