A: I remind myself that in my life, just as in my classroom, certain things are non-negotiable. An important non-negotiable for me is exercise: I swim every morning before school. When I’m stressed, it’s tempting to think about skipping my swim. But I remind myself firmly that lack of exercise will compound my stress and ultimately make me feel worse. The sense of well-being I feel after swimming reinforces my belief that I have to take care of myself if I’m going to have the energy to take care of others.
