How clearly do you think you give directions? I’m not talking about directions to a specific location; I’m talking about giving instructions to someone else so they understand what you want. If you think you are pretty good in doing this, try this activity: sit with your back to a person and give them [do not show them] directions to draw this diagram, or a similar diagram. The only rule is they cannot see what you are telling them to draw.
It’s not as easy as it sounds! Let me know how you did.
Remember, it’s not what you said, it’s what they think they heard!
