“Life is habit. Or rather life is a succession of habits.”

“Habit is a great deadener.”

“Habit is the ballast that chains the dog to his vomit.”

“We have time to grow old. The air is full of our cries. But habit is a great deadener.”

“All I know is that the hours are long... and constrain us to beguile them with proceedings which ... may at first sight seem reasonable, until they become a habit.”

“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.”

“But it is useless to dwell on this period of my life. If I go on long enough calling that my life I'll end up by believing it.”
