Self-Determination Theory (SDT)
A motivational framework identifying three universal psychological needs: Autonomy (choice), Competence (mastery), and Relatedness (connection). When met, people thrive.
Self-Determination Theory (Deci & Ryan, 1985) proposes that human motivation and wellbeing depend on fulfilling three innate psychological needs.
Autonomy: the need to feel in control of your own behavior and goals. Competence: the need to feel effective and capable. Relatedness: the need to feel connected to others. When all three are satisfied, people experience intrinsic motivation — doing things because they're inherently satisfying, not for external rewards.
SDT explains why some jobs feel fulfilling and others feel soul-crushing regardless of salary. A high-paying job with no autonomy, no growth, and no connection will always feel empty. Career assessments (RIASEC + Values) help identify roles that satisfy all three needs.
