The impressive thing about habit is that it accustoms the mind to difficult tasks, making them seem almost, almost easy; and even if it does not go that far, it trivializes doing them, something extraordinary in itself. Psychologically, getting used to doing something means doing it with less effort, like switching on an automatic execution mode. And it is only possible to see how beneficial, how powerful a habit is when one breaks it and then tries to do what one used to do naturally. Almost always, the effort needed to pick it up is less than the effort needed to give it up.
