New research reveals well-being builds self-control more effectively than willpower alone for achieving goals. A study by researchers at the National University of Singapore found that psychological well-being and daily positive feelings serve as essential precursors to better self-control, reversing the common assumption that willpower leads to happiness. Drawing on Barbara Fredrickson’s broaden-and-build theory, the research suggests that instead of forcing discipline to break bad habits, people should focus on restorative activities like practicing gratitude, connecting with friends, and finding meaning to build the psychological resources needed for sustained self-control.
