In psychology, self-determination is an important concept that refers to each person’s ability to make choices and manage their own life. This ability plays an important role in psychological health and well-being. Self-determination allows people to feel that they have control over their choices and lives. It also has an impact on motivation—people feel more motivated to take action when they feel that what they do will have an effect on the outcome.

The concept of self-determination has been applied to a wide variety of areas including education, work, parenting, exercise, and health. Research suggests that having high self-determination can fosters success in many different domains of life.
