Habits are automatic routines of behavior that are repeated regularly, without thinking. They are learned, not instinctive, human behaviors that occur automatically, without the explicit contemporaneous intention of the person. The person may not be paying attention to or be conscious or aware of the behavior. When the behavior is brought to the person's attention, they may be able to control it.

- Monks, these two extremes ought not to be practiced by one who has gone forth from the household life. (What are the two?) There is addiction to indulgence of sense-pleasures, which is low, coarse, the way of ordinary people, unworthy, and unprofitable; and there is addiction to self-mortification, which is painful, unworthy, and unprofitable. Avoiding both these extremes, the Tathagata (the Perfect One) has realized the Middle Path; it gives vision, gives knowledge, and leads to calm, to insight, to enlightenment and to Nibbana. And what is that Middle Path realized by the Tathagata...? It is the Noble Eightfold path, and nothing else, namely: right understanding, right thought, right speech, right action, right livelihood, right effort, right mindfulness and right concentration.
- Whereas some ascetics and Brahmins remain addicted to such unedifying conversation as about kings, robbers, ministers, armies, dangers, wars, food, drink, clothes, beds, garlands, perfumes, relatives, carriages, villages, towns and cities, countries, women, heroes, street- and well-gossip, talk of the departed, desultory chat, speculations about land and sea, talk about being and non-being, the ascetic Gotama refrains from such conversation.

Quotes reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895).
- Habit if not resisted soon becomes necessity.
- Augustine of Hippo, p. 296.
- Give a child the habit of sacredly regarding the truth—of carefully respecting the property of others — of scrupulously abstaining from all acts of improvidence which can involve him in distress, and he will just as likely think of rushing into the element in which he cannot breathe, as of lying or cheating or stealing.

The pleasures are sent for firewood, and the hell begins in this life.
- Samuel Taylor Coleridge, 1st Baron Brougham and Vaux]], p. 295.
