Opportunity: you can buy $1500 in shingles, put them on someone's roof yourself in 4 days, and clear $5000 profit -- somewhere where rents/mortgage are under $1500 a month and a nice restaurant meal for two is under $50.

It's rapidly looking like nerding out while pining for the old days where engineering knowledge and education was valuable is maladaptive. The sunk cost fallacy can be real.
