According to a series of studies done at London University, a team of researchers conducted experiments to assess just how long it takes to turn a behavior into a habit. Each of the 96 participants were instructed to pick one new habit, such as “exercising for thirty minutes each day” and then report their findings. In this study—which went on for several months—they discovered that depending on circumstance, it took participants on average two months (some it took up to eight months) to form a new habit, and become likely to stick with it.
