I built a house in the 1990's that was 6 levels, and had many ceilings of 10 to 14 foot height. The drywallers sent by my contractor were a father-son team. Father was at least 70, and required a cane to walk on level ground. Son was at least 375 pounds. Yet they both somehow assembled and got on scaffolding to complete the entire 5000 sqft house, and did it in a reasonable time frame. I was uncomfortable watching them, but they were good.
That’s the person I’m rooting for! Figures out a way to do it better than anyone else! I hope he takes his drive to be the best and figures out to make a million!
