On this week's podcast, Maddy Johnson joins us to talk about compassion and other lessons from the book Tattoos on the Heart by Father Gregory Boyle. For twenty years, Gregory Boyle has run Homeboy Industries, a gang-intervention program located in the Boyle Heights neighborhood of Los Angeles, the gang capital of the world. In Tattoos on the Heart, he distills his experience working in the ghetto into a breathtaking series of parables inspired by faith.
