What started you down the rabbit hole of scrapping?

Worked building maintenance at a retirement home and the maintenance crew would break down the scrap from the work we did in the building. We would break it down and separate it and when the barrels filled up, we would take it in and split the money between the crew. When I left, I was still puling faucets and sinks and other items I could scrap, as well as picking metal at yard sales. It is money I get for doing stuff I really don't mind doing at times I would be doing nothing.
