My Ts never game me homework. I don't think I would want to do written assignments - I already think and write more than enough on my own. What I would have liked probably is something that requires practical action - putting myself in a situation that I tend to avoid or not deal with properly, and discussing the outcome in session. I give myself challenges like that quite often but perhaps it would have been useful in making my therapy more focused and task-oriented, because most of my problems are related to actions (wrong or lack of action), and dissecting the feelings around them tend to help little. usually it is much more beneficial backwards: do the things and see how I feel about it, what unexpected fears surface on the go etc. Understanding my motives tend to come pretty easily for me, but it's rarely enough for practical change or improvement.
