The Psychology of Habit according to William Ockham

""The facts concerning habit are a commonplace of our every-day existence. All our ordinary actions, like walking, eating, speaking, and the others, are attributable, in part at least, to acquired habits. Our social conventions and our moral behaviour reveal the effect of habits. Success in business, art and the professions is due in great measure to this same force. These observable facts leave little room for discussion. The problem of habit is not whether there is such a thing, but rather how to explain it. What is the basis of habit, that is the question.""--From the introduction.
