I do think that part of the "underlying issues" tidying aspect is that some people need to do a tidying of their dreams before they can do a tidying of their stuff. Which doesn't mean get rid of everything that reminds you of something you used to love! But it can mean being ruthless about how much of the thing you still need around. And it can mean being ruthless about admitting something is over — i.e. if your small business hasn't made any profit in ten years, maybe it's time to pull out a few souvenirs of the good times and dump the garage full of unsold inventory and marketing fliers. And sometimes it's really good to say "what part of the dream is still important to me, and how can I reshape it around that core into something that's still possible?"
