Summarize this article in one sentence.
After realizing that you have messed up something important, don’t take any immediate action. Your emotions will be running high. Your mind will probably be racing. Your heart may even be pounding. Refrain from making any big decisions or taking actions that you might regret later. You probably feel like you need to start working on damage control immediately, but resist the urge. The last thing you need is noise, excitement, and unwanted social interaction. Try going into a bedroom, a private office, or a basement and shutting the door. Consider turning off your phone and shutting down your computer. All of this will reduce the risk of taking impulsive, ill-advised actions. After messing up something important, you will probably be taking short, shallow, and unconscious breaths from your chest. Try to change this. Focus on taking long, deep, conscious breaths from your diaphragm and abdomen. In practice, this feels like you are breathing from your stomach rather than your throat.  Concentrating on deep breathing will reduce your stress level, slow your heart-rate, and provide more oxygen to your system. People have been using this type of breathing for thousands of years through yoga and meditation, and it is scientifically proven to help manage stress and anxiety. Don’t allow your thoughts to keep going back to what you messed up. Stop your mind from racing towards the future consequences of your mistake. Achieving mindfulness means focusing on the present, your immediate surroundings, and your body. Become aware of your own sounds, the temperature, and what you smell or feel. Doing so will help you to relax.

Summary:
Pause for a few hours. Find a quiet, solitary place. Focus on your breathing. Try to achieve mindfulness.
