I saw a T for a few sessions when I was having intense anxiety during pregnancy. A vision board (or something like that) was one thing she wanted me to do (along with getting involved in some sort of religion). At the time, it was not helpful and like the opposite of what I needed. So I stopped seeing her.

Not sure my response is particularly helpful, but I just don't necessarily see the value in such an assignment, unless it's something the client wants to do (which seems like it was the case for you, Art!)
