The "3, 2, 1 (Countdown)" is a simple technique used to help individuals focus and prepare for a task or transition. It involves counting down from three to one, which can create a sense of urgency and readiness. This method is often used in various settings, including classrooms and therapy sessions, to encourage mindfulness and concentration. In practice, a person might take a moment to identify three things they can see, two things they can hear, and one thing they can feel. This exercise helps ground them in the present moment, making it easier to manage anxiety or distractions before proceeding with an activity.
