Dave Brewer has been a therapist for over 35 years. In today's podcast he lists out the 9 things he would like you, the client, to know. 
Those are:
1. I'm not judging you. That which you fear is most unique about you is often most common among people. 
2. Change takes time. Be patient with yourself and others. 
3. Take a risk. What would you do if you were not afraid?
4. Trust me, tell the truth, the whole truth. I can't read minds.
5. If you want more out of it put more into it. Practice at home. 
6. I hope our relationship will be empowering for each of us. 
7. Sometimes I need to think about your issue or do more research.
8. Share your expectations. Do you want me to listen deeply and understand; or are you looking for feedback and suggestions?
9. Give me feedback. Let me know what's working for you and what's not helpful.
