Calm is like setting a thermostat at the right temperature for keeping a house cool on a blazing hot summer day. But if there are doors and windows that stay open, letting the heat in, you’re still going to feel the effects of the outside heat. The wrong tactic would be to stand at the window, telling the heat that it can no longer come inside your house. The right tactic would be to shut the windows and doors and let the air conditioning unit work to accomplish the atmosphere you want.
