A simple requisite of mastery in any domain is age. Not to say that young people can't be brilliant and impactfull at their craft. But such qualities fall more rightfully described as having flair. The difference between mastery and flair is that the former is more reliable and stable. As an art teacher, I have seen many young artists go on to have great careers shortly after leaving school... but most of them burn out or fail in one way or another. Conversely... their aged teachers have acquired character, depth and stability but have in the process lost their wildfire.
