The document discusses the importance of clarity of purpose in group leadership. It states that having well-defined objectives and following the stated objectives helps ensure that the leader keeps members on track. When the leader is unclear about the purpose, groups can become confusing, boring, and unproductive. The leader must assess members' needs to determine the appropriate purpose of the group and clarify the purpose during the first session. While groups can sometimes have multiple purposes or changing purposes, clarity of purpose is especially important for single-session groups.
