Or just start now.
I told my wife that if I ever became terminally ill, I would like to spend a chunk of my time (as much as I was able) working on publishing a list of writings that I would want those who wanted to honor me to read. These would be a list of works that I found incredibly valuable, heavily-influenced my thinking, and I believe have the effect of making the world a better place. She asked me why I don’t just start now (she’s a wise one), so here we are:
Letter from a Birmingham Jail - Martin Luther King, Jr.
Changing Lenses - Howard Zehr
Maciej Ceglowski’s talks
