21-Day Reading Habit Cultivation:Tracing the Source and Reflections on the Practice
This paper traces back the source of the"21-Day Habit Cultivation"trend,as it has become a popular reading promotion activity in libraries.Through literature retrospective,we found that the idea of"21-day Habit Cultivation"originated from Maltz's Psycho-Cybernetics.There is a cognitive bias between the popular belief in"persist for 21 days to form a new habit"and Maltz's"it requires a minimum of about 21 days for a new mental image to jell".The study also provides a comparative analysis of 21-day reading habit cultivation activities and offers thoughts and suggestions on library's reading promotion.
