"I have found that corrections done in a firm and fair manner with an explanation are appreciated, not resented. Always try to turn the encounter into a mutually positive learning experience. These truths are known to every good classroom teacher, every good coach, every good violin teacher, and every good construction foreman. Mistakes that have become deeply rooted habits- in a batter's stance, in a violinist's fingering, in a child's table manners, in a roofer's roofing skills- drive teachers, coaches, foremen, and parents nuts. You have to catch them all early, and properly train the correct actions, skills, and behaviors. Leaders who do not have the guts to immediately correct minor errors or shortcomings cannot be counted on to have the guts to deal with the big things."
