You don't communicate solely in words.
We've all been in the situation where we can see someone saying “Yes” when they mean “No!” That's because our body language also speaks volumes about how we feel.
A good coach can help you examine your own messaging for congruence. Sometimes we're reluctant to say how we feel about something particularly if we're in a position of power and it would make us feel weak. Your coach can help you work with your values instead of against them to get what you need.
Ask yourself: Are you aware of your body language?
