William Glasser

William Glasser was an American psychiatrist best known for developing Choice Theory and Reality Therapy. He believed that human behavior is driven by the desire to satisfy five basic needs: survival, love and belonging, power, freedom, and fun. Glasser emphasized that individuals can choose their behavior and that mental health is tied to fulfilling these needs through personal responsibility and effective relationships. His work has influenced education, therapy, and management, advocating for a supportive and non-coercive approach to helping people improve their lives and interactions with others.
