In the early 1970s, psychologists Edward Deci and Richard Ryan developed a concept called self-determination theory that forever changed how the scientific community viewed motivation. Deci and Ryan found that, contrary to common wisdom (both then and, to a large extent, now), one’s drive to pursue activities is not predominantly reliant on external rewards like money, fame, or recognition. Rather, enduring motivation comes from satisfying three basic needs: competency, autonomy, and relatedness.
