Calm first...rationalize second.
The Amygdala is the part of the brain that pumps adrenaline into the body and reacts in situations that are emotional and/or threaten our safety. It is the part of the brain that tells us "there is a bus coming! Don’t cross the street". When a person is upset and yelling it doesn’t matter how sound your logic is, we are not built to rationalize in the heat of the moment. The quote in the caption would be good advice if we were capable of taking it when we needed to. Since we are not at our best when we are frustrated, we have to start somewhere else in these situations. Calm first... Rationalize second.
