Eye contact is necessary – look the person in the eyes
Be aware and attentive – show interest. Nod your head, lean in, show some interest.
Don’t interrupt – wait for a pause before you jump into the conversation.
It might not be your idea, opinion or even a fact but relax and take it in. It’s OK to disagree just do it graciously.
Don’t try to think ahead about your response because you’ll miss half of what they say.
If everyone tried to actively listen to each other I think there would be less communication problems.
