Habit
A habit (or wont, the original word in English) is a routine of behavior that is repeated regularly and tends to occur subconsciously. The concept of habit has been widely discussed in psychology and philosophy, particularly in the works of William James, who described habits as the "enormous fly-wheel of society." A 1903 paper in the American Journal of Psychology defined a "habit, from the standpoint of psychology, [as] a more or less fixed way of thinking, willing, or feeling acquired through previous repetition of a mental experience." Habitual behavior often goes unnoticed by persons exhibiting it, because a person does not need to engage in self-analysis when undertaking routine tasks.
