As I approached 40, I changed my health and lost fifty pounds. Equally striking to me was the reaction to my Medium post about the experience. I wrote it so I could stop retelling the story of how I lost the weight, including students scheduling office hour meetings to discuss. The piece got 4K reads and hundreds of recommends. I had a geek-moment when I saw Ev Williams (Twitter co-founder and creator of Medium) highlighted some phrases. Strangers wrote me how I inspired small changes to their health behavior. I truly understood what it meant to be my own channel.
