Philippians 2:3 Do nothing from selfish ambition or conceit, but in humility regard others as better than yourselves.
I suppose every team has a troublemaker.
As a Naval officer I had to learn everything about the equipment under my care and manage a team of technicians. Unfortunately one technician liked to use his technical know how to sass his peers and his supervisors, which meant me.
In order to qualify on my watch station I had to demonstrate my knowledge of the entire plant, including the piece of equipment that this irksome petty officer maintained. I may have had superior knowledge of the underlying physics, and the interdependence of this machine, but he proceeded to quiz me on the location of test points and set screws, some of which were hidden.
I am confident he asked me these questions to puff himself up. But in do so, he taught me how we know differently, not better than one another.
What lessons have you learned from a troublemaker?
