My T has said I'm a good patient because I'm interested in the therapy process and I'm willing to do the necessary work (most of the time, anyway!) She said lots of clients just expect her to magically fix all their issues and don't want to put in any work. So, be willing to do work, whether it's talking about stuff in session or doing other things outside of session.

Plus basic things like showing up on time, calling if you have to cancel rather than no-showing, etc.
