At first, doing something different or even just more than you did before, is an effort. If you keep doing it with good reason and with intent, it will eventually become a habit.
21 days to form a habit is a myth, that’s peddled especially well by apps that want your attention. A scientific study found variation of between 18 and 254 days, depending on the individual. 66 days was the average.
If it’s worth doing, persist. What feels like effort will be a beneficial norm in time – and then you can level up again.
