1. The pause button.
The pause is as simple as taking a moment to stop and think before we act or speak. This is especially helpful in a situation where our emotions run high, because it can prevent us from saying or doing something we'll later regret.
Just remember: The pause is easy in theory, difficult to practice.
Factors like added stress or an unexpected situation can easily catch us unawares. That's why it's important to train yourself to use the pause regularly. This will help you to create a habit of thoughtful action. (More on the pause here.)
