The Three-Sentence Rule is a framework that allows people to slow down, think about what they want to say, and package it in a way that makes sense and engages others.
To keep your messages short and simple, get to the point faster, increase your self-awareness, improve the quality of what you say as well as speak more succinctly, experiment with the following structure:
Sentence 1: Purpose (or Problem)
Be purposeful with your first sentence and/or articulate the problem, bottom line. Effectively grab your audience. Make sure they understand that what you are about to say is important. Get their attention.
"I’d like your opinion on something important."
"You sound worried about this forthcoming presentation."
Sentence 2: Point
Get to the point with your second sentence. Validate sentence one with some data, facts, or important information. Be clear about the goal. Make it simple and straightforward.
"We are looking to restructure our service, with X in the lead."
"I have experience and time to explore this with you if you want."
Sentence 3: Progress
Make progress with your third sentence by asking the curious question and then stopping. Wait as long as you have to for a response from the person you are communicating with. You now have people engaged in a dialog with you.
"What do you think?"
"How can I help?"
At this point if the listener wants more information they can ask for it without you offering up more than you need to.
