This is a simple concept I’ve used a lot the coaching of others.
I often watch people in an interview, or a sales call, ramble on in response to a question. In many cases, it’s as though they’re doing the thinking WHILE they’re talking.. and the model I have in my head is that of exploding fireworks. They start talking about one thing, the FIND a point and then explode into a new direction around that point… and then another direction… and so on.
Think instead about the mental image of throwing a dart to answer the question.
Stop. Think about what point you want to make. Throw the dart. Then stop talking.
