noun
habit
HAB-it/ˈhæbɪt/
An established recurring pattern of behavior.

Etymology
Habitus described both outward appearance and an inner state or disposition. The inward sense connects habit with a person's customary way of acting, rather than with the clothing sense preserved in a monk's habit.
In context
if you repeat something several times in the same way you will have formed the habit of doing it that way but the oftener you repeat it the stronger that habit grows
