To start with--I have a very small sewing room. I once put pics on here on another section of the board.
Secondly, we were preparing to move across country which forced me to pick up every piece of quilting fabric, tools, etc. Many UFO's were given away as it is expensive to move stuff. I resolved at that time to stop doing this.
I have done BOMs that take months to complete. I don't count them and now chose just one if any. I have a few of my own kits cut and ready to sew. I don't count those either. They are ready to grab and go for a group sewing day.
It has given me more peace. I am mainly a charity quilter so my projects are not complicated. It keeps the mess out of my small space.
If one is happy with many projects---that is fine. I was tired of it and felt like they were all calling to me...lol.
