A danger is that over time the rules and routine may become a rut of monotony, and we will be stuck in a pattern of living that is emotionally deadening. Our habitual routine may provide a set of blinders to a more exciting and challenging life. To break out of routine you can be deviant. You can do something different on purpose. It may be as simple as changing the way you drive to work.
Tomorrow go a different way.
Leave earlier if you have to. See something different. Take the scenic route. Be open to the experience and see if it brightens your day. Do the same thing on your way home.
