"It takes 30 days to break a habit. A habit is a settled or regular tendency or practice, especially one that is hard to give up. If you check Facebook every day that it is possible to do so, I would consider that a habit. If you check Facebook more than once a day, I would consider that a habit. If you turn to Facebook as a way to relieve boredom, I would say that is a habit. If you check Facebook often, regularly turning to it as a way to relieve boredom or to find “someone to talk to” and find yourself using it instead of doing something more fulfilling, which to you could be knitting a sweater vest but to me would be something more like finishing that goddamn David Foster Wallace novel despite how tiring the footnotes are getting, than I would say that you may be addicted."
