Antoni,
Great question and probably one that would be best answered by someone who does touch therapy. But I would think its alot like therapy. There's a lot you can learn, but the people who are really gifted seem to have something integral to who they are, an extra gift of empathy, that I don't think you can learn. You just have it or you don't. I think someone without it can learn to be a "good" therapist, but for "great" you need to have something in you. Just like some people can rise to become professional athletes, its an inborn talent. Just my humble opinion.
