Are you a thermostat or a thermometer? You are one or the other. A thermometer registers the temperature. It simply reflects its environment, whether it’s hot or cold. A thermostat, on the other hand, controls the temperature. It influences its environment; it sets the standard. Which are you – a thermometer or a thermostat?
