When I was a Martial Arts student, my teachers would give the entire class push-ups for the wrong-doings of a single student.
I hated being punished for things I didn’t do that were also out of my control. It made me resent them in many cases.
So, I resolved to never do that to a class when I became a teacher (Yes, I knew I wanted to be a Martial Arts teacher long before I ever was).
Now, the motto that I have worked tirelessly to embody is praise publicly, reprimand privately.
No longer is the attention of the class pointed towards the students’ wrongdoing—now it’s pointed towards the students who are doing things right. And the students who are doing wrong get a private conversation from a more experienced instructor who can compassionately help them understand and change their behaviors.
Had I not felt that resentment and planted that seed in my mind when I was a student all those year ago, maybe I never would have felt the need to change that tradition when I was in front of a class (with misbehaving students) all those later years.
You can learn just as much from the people who do wrong by you as you can from the people who do right by you.
You just have to keep an open mind and learn how to channel your negative emotions rather than let your negative emotions become you.
