When you are not harping technique it is time to shut up and listen. Let your clients tell you how they feel. Empower them to communicate by asking strong open-ended questions and then actually listen to their response and jot it down after the session. You will be able to draw on this information later and it will probably help you more than you think. Bringing up a topic that was important to the client a session or two down the road will show them that you are listening and care about what they are saying.
