When communicating, consider adapting the personal mantra: pause, acknowledge, and then act responsibly. Even pausing seconds will help re-focus your intentions.
It gets down to training yourself to control your natural tendency to be impulsive. You don’t want to get into the habit of overreacting to every situation, whether shooting from the hip, having loose lips or, even worse, causing others to anticipate your tendencies to do so. Before you open your mouth, or write and tap with your fingers, pause to anchor yourself.
