I teach others to value difference, particularly gender and generational differences. I need to learn to value one type of difference that is unrelated to gender or age – the difference between “A-type” and “B-type” personalities. As an “A-type,” I move quickly from one task to another and want things done now. “B-types” take things more slowly and like to do one thing at a time. We can drive one another crazy – or we can recognize difference and appreciate strengths different from my own.
