“Yes, a habit can be completed in just a few seconds, but it can also shape the actions that you take for minutes or hours afterward. Habits are like the entrance ramp to a highway. They lead you down a path and, before you know it, you’re speeding toward the next behavior. It seems to be easier to continue what you are already doing than to start doing something different. You sit through a bad movie for two hours. You keep snacking even when you’re already full.”
