I never dreamed my zest would be gone by Weds. Now, I depend on thyroid replacement. I am a nurse-midwife and wellness coach. I am challenged by this . . . I practice positive psychology daily to stay resilient. Positive emotion . . . engagement in life . . . relationships (positive friend/family/community links) . . . meaning in life . . . accomplishment. Those are the ingredients of flourishing according to Dr Martin Seligman, the father of positive psychology - the science of happiness. I can't do as much, but I can flourish.
