Coronavirus Series, Part III: MENTAL HEALTH. Carly Sullins is a ray of sunshine. Ever since I met her, she has inspired me to choose joy on a daily basis. But what happens when the sunshine runs out? In today’s episode, I have two conversations with Carly, each 5 months apart, discussing the ups and downs of “maintaining the sunshine”. We discuss our sine and cosine theory of mental health, our blindly ambitious coronavirus goals, and the importance of puzzles.
