Self-actualization is a term used to describe the highest level of psychological development a person can attain—our “fullest potential.” The term was coined by theorist Kurt Goldstein, though used extensively by humanistic psychologists Carl Rogers and Abraham Maslow. It captures the idea that with the availability of the right resources, circumstances, and introspection, we can tap fully into our mental, physical, emotional, and spiritual capacities, living as our “true selves.” Strategies for attaining self-actualization differ, but most are flexible to accommodate a range of philosophical and religious worldviews.
