I gave a talk this morning to a group of management consultants at the Accenture headquarters in London. Not an easy audience, you’d think, but they seemed very open to the idea that slowing down might be good for them, the company and the world in general. Afterwards, a woman from the audience told me about the incident that persuaded her it was time to put on the brakes. She spotted a good friend in the street but, deciding she was too busy even to stop and say hello, ducked into a shop to avoid catching his eye. He died suddenly a few days later and so the next time she saw him was at his funeral.
