I like the definition of stress presented in this course: conflict between goals and capabilities.  Sure makes sense to me.  Some weeks I am very organized and on top of my game.  Other times I am not where I want to be, but these moments or days are quick and don't come around often.  Though, there are those more stressful days and the headaches that acompany them. After many years of teaching I don't expect everything to go smoothly. Taking the time to keep up on paperwork helps.  I finally realized that letting things go when stressed is okay if it doesn't affect my job or my students.  Giving up daily caffeine and making time to exercise has made a big difference for me.
