Just today a student of mine was discussing stress management in a live chat. He said you have to "archive" how you successfully deal with stress so that you can bring out the technique again later. I loved that! For me, choosing what to confront and what to avoid is a big deal. I have effectively decided to "choose my battles" when it comes to work, teaching, parenting, life, etc. There really are things that are out of my control (environmental stressors). I can work mostly on personal frustration and do my best not to be my "worst enemy".
