I don't look at it as overcoming SMAD but rather moving on. I think it's a thing that changes as our interests change. The harder part is if the working on them doesn't keep up with the accumulating part. I'm in a stage of flux right now but I think it's just the holidays. I've been away from the tinkering and it's cold and damp outside. I may start up the woodstove and see if something catches my interest. I have plenty to work on for now and I know once I get a start on it, it will catch me up in the process for hours.
I've been working on my sewing room. It's a work in progress but it evolves as I need it.
The Pfaff 30 came out lovely! If you don't have a desire to hold onto it, I know you can find a good home for it. Your interests are changing and that's ok.
