A decade or two ago I talk with a 90 year old who bought, sold and especially exchanged everything not bolted down since he was 12. He had a crappy shed he filled with all kinds of garbage/treasures. I wouldn't call it a business. He did have businesses later on but that wasn't his primary activity. He would trade some old wood stoves for goats that he traded for a boat. That's not a business model is it? He obtained one classic car that took many years to get back on the road. Not really a business? I barely knew the guy but know enough hilarious stories to fill a book. Without that shed however he wouldn't have happened.
