I kind of do.
I switch out all of our wardrobes seasonally. This takes at least an afternoon, during which I try on all of my clothes, get rid of things that I haven't worn that season or that I have put away for next season that I realize I won't be wearing. I also go put away DD's out of season clothes, sorting them into things to throw away, donate, save that might still be large enough next year, and sell, and take out her new ones. This usually results in a huge goodwill pile, which then prompts me to go through the rest of the house to find things to add to it (since I'm taking it to Goodwill anyway). So, tons of stuff is donated at least with the change in seasons 3-4 times a year.
I also sort mail and paper trash as soon as I get it, but have a tradition of going through our files and recycling things that are no longer needed over my xmas break.
I really don't like clutter and find organizing/getting rid of it relaxing, so that's a good motivator.
The one area we could use improvement in is dirtier storage like our basement and barn. They could probably use a good going through more often to get rid of trash, boxes, etc. But, DH is more of a pack rat, and these are more his domains, so to a degree I leave them alone for his sake.
