Students choose this profession based on a belief that with good intentions and a love for helping people, all clients will benefit and flourish from their services. Unfortunately, not all clients want to change, or they are unable to, for a variety of reasons. Some clients will be grateful, some won't progress the way you would have hoped. Every client's life will be touched by you in different ways. It's good to be realistic about what to expect when going into this career.
