“When I speak in casual conversation, I try to start a mental clock in my head. I actually learned this from Marty Nemko, a San Francisco career coach. He told me, “For the first thirty seconds after you start talking, imagine a green light in your head. After thirty seconds the light turns yellow. At sixty seconds, it’s red.” That’s a good piece of advice for most any conversational situation. It takes some mental energy to monitor myself, but it works.”
