Years ago, Jon had set up an important team meeting for 10 a.m. At 9:45, he was setting up the room. By 9:50, he was ready to start. By 9:59, no one had arrived. “I had a decision to make,” he says. “What if I started the meeting on time—all by myself?” That’s exactly what he did. That’s why “Just start it” is now his No.1 rule for holding meetings that start on time.
