Advice to keep decluttering?

My wife and I moved a couple times in the last few years, and we’re now in our own home. I decluttered quite a bit between moves, but I’ve kind of hit a wall with decluttering. I’m really satisfied with how much I’ve cut down my wardrobe, but overall, I feel like there’s still a lot of stuff that has no home, and an overall sense that there’s too much stuff that is unused and not valuable to us.

How can I get the motivation to keep going. Any tips and tricks, or “rules” you’ve employed when you’ve already gone through your things so many times?
