I don't consider myself a musician who has achieved perfection and can't develop any further. But I compose my pieces with a formula that I created myself. Take a musician like John Coltrane. He is a perfect musician, who can give expression to all the possibilities of his instrument. But he seems to have difficulty expressing original ideas on it. That is why he keeps looking for ideas in exotic places. At least I don't have that problem, because, like I say, I find my inspiration in myself.
