Ho’oponopono is a hawaiian ancient expression, a possible key to happiness. Repeating the words of „thank you” and „I love you” it is easily achievable to keep ourselves in the present stopping our mind to take us into the past or the future. This way we become free of stress and fear and we can’t stick into any problems. To this, practising tennis contributes with discipline, endurance and precision. Tennis is often called the king of sports because it is all about the harmony that reflects in the complex movements of the body and the limbs.
