"If one has the talent it pushes for utterance and torments
one; it will out; and then one is out with it without
questioning. And, look you, there is nothing in this thing of
learning out of books. Here, here and here (pointing to his ear,
his head and his heart) is your school. If everything is right
there, then take your pen and down with it; afterward ask the
opinion of a man who knows his business." -- W. A. Mozart

(To a musically talented boy who asked Mozart how one might learn to compose.)
