"It is very difficult to make good mistakes."

Thank you for that video, PP.
I also loved the idea at 3:00 of the bearded Scottsman screaming at the German soldiers.
I was fortunate to work for a crazy farmer for many years who was obsessed with fruit and vegetable varieties. Quality of taste was everything - nothing else mattered. In the 70s, he once had a university professor come to his farm to find out who it could possibly be that was trying to patent 17 new varieties of black raspberries at once. In his later years, he was invited to the White House with many farmers being recognized for their work.
Your video reminds me of his style - never listened to the universities - always trial and error on his farm, his soil, his weather.
Great video for every aspect of society.
