Depending on the situation, clients can be assigned homework. I give homework for a reason! It can increase the effectiveness of your sessions and can accelerate the counselling / coaching process.
If it is any consolation, I do homework for you too. I write case notes for me to understand what is happening, and it gives me a chance to reflect on the session and identify any areas that need addressing that may not have been so obvious during the session. I also plan for your next session, so we can try to cover as much ground as possible.
