And, the only way to never make a mistake is to never do anything; the only way to never be wrong is never to say anything, etc.
When I was a factory foreman there was a guy in another department I always snatched up to work in mine if possible. He clearly wasn’t very bright so I wouldn’t have trusted him to mix paint or measure viscosity or anything like that but he was a machine when it came to simpler jobs. He was better than the people in my own department because he didn’t see those jobs as beneath him like my prima donna painters did.
