Sometimes we might not do a great job because we didn’t know what we were doing and other times we were geniuses because we had messed up so many times before that we finally figured out how to do it right.
As I grow older, I find this is how you become an 'expert'. You start not knowing how to do it, then you figure out all the wrong ways to do it by doing it wrong. Eventually, when you have messed it up in more ways than anyone else you know which paths not to take and you are then the expert.
From the Reuters article on the same topic:
Trump made several visits to cities with large Arab American and Muslim populations, include a stop in Dearborn, a majority Arab city, where he said he loved Muslims, and Pittsburgh, where he called Muslims for Trump "a beautiful movement. They want peace. They want stability."
'They will be peaceful when they are dead'
