Compulsion.

Music suited me, because, I think, that in order to be a musician, one has to be compulsive. There is an innate compulsion, as in every other activity that requires a search for perfection. I think that all children who play an instrument or practice a sport have this in them. From the outset, one needs to have a certain way of thinking that is practically pathological, and at the same time a certain exuberance, an expressive strength of communication.
