Step One is Start With Yourself. Starting with yourself id basically just you knowing yourself, what you value, how do you relate to people, and many other questions. Step Two is Think Of Others. This basically is, who is your audience, is it an individual or group, and that type of stuff. Step Three is Tailor Your Message To Your Audience. Tailoring your audience is basically speaking to their values, motives, and interests.
I hope this helped!
