William Glasser developed reality therapy, which focuses on helping clients make responsible choices to meet their basic needs and improve their lives. Glasser believed human behavior is driven by five basic needs: survival, love, power, freedom, and fun. Reality therapy techniques encourage clients to evaluate their current situation, make action plans, practice new behaviors, and improve relationships to close the gap between their desired life and reality. The goal is to help clients gain a sense of control by making choices that lead to more fulfilling and productive lives.
