Thermometers read the environment and indicate the temperature of the room. Thermostats adjust and control the temperature of the room to return it to the desired state. Thermometers are fairly simplistic devices that do one thing. Thermostats are more complex and are able to either heat up or cool down an environment, depending on what is required. Thermometers react to the environment. Thermostats change the environment. We can be thermometers that allows our attitude to merely be a reaction to our situation. We get hot when we are upset or we curl up in a ball when things don't go our way. That is what a Thermometer does. However, we can choose to be a thermostat that reads the situation and then adjusts our attitude to bring the environment back to the proper condition. We have more functions than merely one and we have the ability to adjust.
