1. As soon as you notice that you are distracted, find a quiet place where you can be alone.
2. Sit with eyes closed and take a few deep breaths or sighs.
3. Place your attention in the center of your chest in the region of the heart.
4. Continue to breathe normally for a few minutes until you feel calm and centered once more.
The trick is repetition. You need to center yourself as many times a day, or an hour, as you need. Need is indicated by feeling bored, sad, anxious, angry, or dull.
