Great article from Harvard Business Review on the “Traffic Light Rule”. Is this the same for optimizing content? What rule would you apply?

First 20 seconds of talking, your light is green: your listener is liking you, as long as your statement is relevant to the conversation and hopefully in service of the other person.

Second 20 seconds of talking, the light turns yellow for the next 20 seconds— now the risk is increasing that the other person is beginning to lose interest or think you’re long-winded.

At the 40-second mark, your light is red. Yes, there’s an occasional time you want to run that red light and keep talking, but the vast majority of the time, you’d better stop or you’re in danger.
