The Wheel of Life is a circular self-assessment tool created by Paul J. Meyer in the 1960s that enables individuals to evaluate satisfaction across major life domains using visual scoring. Originally developed for Success Motivation Institute (SMI), this coaching instrument has become a foundational framework in personal development, helping practitioners identify imbalances, prioritize improvements, and track progress over time. Unlike binary goal checklists, the Wheel reveals nuanced satisfaction patterns through segmented visualization, making abstract life balance tangible and actionable. The tool's enduring value lies in its ability to transform subjective feelings into measurable baselines that guide meaningful change.
