The Optimum Way to Break Bad Habits

Breaking bad habits requires self-control — and lots of it. Research indicates that it’s worth the effort, as self-control has huge implications for success.

University of Pennsylvania psychologists Angela Duckworth and Martin Seligman conducted a study where they measured college students’ IQ scores and levels of self-control upon entering university. Four years later, they looked at the students’ grade point averages (GPA) and found that self-control was twice as important as IQ in earning a high GPA.
