Banishing bad habits and converting them to good ones is not easy. As Mark Twain once wrote, “Habit is habit, and not to be flung out the window by any man, but coaxed downstairs one step at a time.” But how do we coax the bad habit down the stairs and out the door while encouraging the new one up the stairs and into the parlour?  Changing a habit takes several concrete steps; you cannot just make a proclamation about your weight or introversion and expect that it will come to pass.
