I agree with this one. Early in my career I was highly competent (modesty aside) in my role and thought the results spoke for themselves. I was coached to say more and put comments in the context of the task to which I was assigned. Lession learned too well.

When people's eyes were glazing over as I spoke, I realized that the best approach is to deliver the message concisely and ASK if the executive (now my position) wants more information.
