That's a tuff problem for sure. What's more of a problem is shutting down two buissinses. Selling off the equipment was fairy easy other than the items that were still being deprecated on taxes. Tax ID's just about never go away, not to mention things tied to your SS#. Personal buildings that are tied to business assets because they were used in the buissinses and built on your personal property means major tax problems if you don’t keep some business going. Paperwork nightmare to say the least. At least I had sense enough to not involve my cars and parts in either of the buissinses.
As to your problem, I'm afraid I'm finding it hard to let go of a lot of things, but I know much has to go. I'm starting with things that I know I will never use. For instance things I removed from cars when I started restorations and were not worthy of being reinstalled. I'm hoping that selling things will encourage me to move on to selling more and bigger and better things.
