I do not feel that any of my therapists have taught me anything (except that it is foolish to trust therapists). Perhaps they helped me unlock stuff I already knew. (I have also never regarded the Huffington Post as the last word on anything.)

Although I have adopted parts of No. 3's email style for emails with students. It seems to make them feel like I care for them. So, OK, I learned how to hoodwink people.

You can learn a lot from other people, una is right. But people go to therapy for all kinds of reasons. Learning may be one of them, but hardly the only one.
