LONDON -- This week began with the continuing fallout from the killing spree at UCSB. Richard Martinez, whose son was among the victims, blamed "craven, irresponsible politicians and the NRA." Echoing that outrage, and the senselessness that lets it continue, the Onion nailed it: "'No Way to Prevent This,' Says Only Nation Where This Regularly Happens." On Wednesday, Maya Angelou passed away, and the world mourned the poet, teacher and thinker who inspired us to look within, reach out and celebrate our common humanity. In in-house news, I was in London, where I found the mindfulness revolution in full swing. As Headspace founder Andy Puddicombe put it, "Ten years ago when I left the monastery I wouldn't have thought I could have a conversation on mindfulness in the pub, let alone with the Chancellor of the Exchequer." As the new week begins, we can let Maya continue to guide us: "Try to be a rainbow in someone's cloud."
