Enthusiasm and Intensity.
The Quality that separates the professional table tennis player from the amateur more than any other is the level of intensity the professional brings, not only to his matches but to every ball he plays in every training session.
Table Tennis matches are very short and require frequent bursts of immense speed and power.
A lapse in concentration can often cost you a match.
The professional knows this and has trained themselves to be vigilant and strong physically, mentally and emotionally.
Most players can improve substantially by simply learning to concentrate all their energy on every point they play in matches and in practice.
