For the past several years, I’ve written an annual letter to family, friends, and colleagues. It’s both an update (since I don’t post much about myself on social media) and a reflection on the previous year. Shuffling between the U.S. and China during college, I started writing the once-a-year missives as a way to keep in touch with people I don’t see often. However, I never expected how transformational and therapeutic the practice would become.
