What does it look like to "work hard" in therapy?

I see my T twice a week, I bring things up to her that I wouldn't dream of talking about anywhere else, and express things to her that I can't believe are actually escaping my head. I journal between sessions, I read on this message board, I even try to read therapy-related books/articles that might be helpful.

I am good at working when I know what work looks like, but I can't figure out what this kind of work looks like! I do intend to talk to my T about this, maybe...
