First off, best wishes on your health. I always tried to buy stuff if I have a need for it. Starting out I had a borrow 3 times, I need to own it rule. When I switched jobs from cars to farm tractors, a lot of tools went idle. I started doing a lot of auto side work, which involved more auto special tools. I have slowed down my side work, so there is eaisly $5000 worth of specialty tools that maybe get used once a year. For a while I had more money then sence and a lot of "shiny tool day". Then I switch brands of equipment, so a fair number of tools I used everyday just sit. Where I work now has limited shop tools with a tight fist owner. Thats fine, I'm the type of guy who likes owning his own. So if I ever change jobs, there will more tools that will most likely sit.
