Both my parents were licensed auto mechanics and worked to repair appliances and eventually installed garage door openers. They also bought a 2 bedroom house (fixer upper) in their mid twenties, raised three kids and paid it off in a timeline that wasn't todays 30 year mortgages.
It's kind of depressing how un-attainable all those things are. I managed to attain a small percentage of this after getting a college degree and working in STEM. It's kind of ridiculous.
