My Uber driver today: Drove 90 hours/week for last 8 years. Lives in his car. Moving back to Georgia in 2 years (country, not state). He's used his Uber earnings to buy 8 rental properties + develop 16 condos back home. When he moves back, he'll have his extended family's expenses covered for life at age 32. Hero.
