In a previous post recently I briefly discussed habits and working towards change. Three weeks to build a habit is an educational message – translational research – that has been shown to be inaccurate. Newer research suggests that two months may be more realistic – an average of 66 days.
I haven’t read the original research for either recommendation however a discussion of how habits can save energy while the use of will power actually seems to deplete our energy, and can lead to less ability to stick to a plan and act impulsively, is available here: Strengthen Your Willpower by Creating New Habits, by Isaiah Hankel, Ph.D. (https://www.isaiahhankel.com/strengthen-your-willpower-by-creating-new-habits)
