Habit is heaven's gift to us:
a substitute for happiness.

Habit is Heaven's own redress:
it takes the place of happiness.

Thus heaven's gift to us is this:
That habit takes the place of bliss.

Habit is a compromise effected between the individual and his environment, or between the individual and his own organic eccentricities, the guarantee of a dull inviolability, the lightning-conductor of his existence.

HABIT, n. A shackle for the free.

Habit is a second nature.

Habit is a cable. We weave a thread of it every day, and at last we cannot break it.

Wealth and all its good things becomes with us at last habit. And habit is life.

The purpose of a habit is to remove that action from self-negotiation. You no longer expend energy deciding whether to do it. You just do it. Good habits can range from telling the truth to flossing.

Habit is stronger than nature.

Habit... makes the endurance of evil easy (which, under the name of patience, is falsely honored as a virtue), because sensations of the same type, when continued without alteration for a long time, draw our attention away from the senses so that we are scarcely conscious of them at all. On the other hand, habit also makes the consciousness and the remembrance of good that has been received more difficult, which then gradually leads to ingratitude (a real vice). [...] Acquired habit deprives good actions of their moral value because it undermines mental freedom and, moreover, it leads to thoughtless repetitions of the same acts (monotony), and thus becomes ridiculous.
