We all want the same things. Start there.
Increasing communication influence

Sketch animation by Michael Taylor ©2021
50% of what you need to know about your customer you already know.
Because you share one huge thing: you are both humans. Being human, you can safely guess they want mostly the same things you want: to be respected, to feel safe, to leverage their strengths, and to get noticed for doing good work.
To greatly increase influence, use the 50% you know as the context for what you are communicating. Ask yourself, do I need to help the persons I’m speaking to feel safe about what I am proposing? Is there any way my proposition helps them use their potential and shine? What are the objective improvements I am offering and the emotional hurdles or supports I need to address that block or support my proposition?
When you aim to understand first, you immediately connect on a deeper level because you have made understanding itself an influential part of your communication.
