In my research on happiness, I keep running into the assertion that it takes twenty-one days to develop a new habit -- but I’ve always had my doubts about the validity that number.
First, when it comes to developing a bad habit, two repetitions is probably enough. Order a doughnut with your coffee on Monday morning and Tuesday morning, and you’ll probably find it very hard to resist ordering a doughnut on Wednesday.
Second, at least for me, twenty-one days isn't nearly long enough to form a good habit.
