This really speaks for itself... incredible.
Many a young person would like to become a doctor or a top-flight scientist but never will, simply because he will not buckle down to the demanding years of hard study. Many young people would like to achieve artistry and mastery in music but they never will, simply because they will not face the long hours of monotonous practice year after year. They may through natural talent become singers or pianists of a sort, but they will not pay that extra price for true excellence. They are too lazy and self-indulgent to pommel themselves to the top. Their ambitions may not be beyond their capacity, but they are beyond their discipline. The world is full of naturally brilliant people who never rise above mediocrity because they will not make the sacrifice which superiority requires.
-- Richard S. Taylor, The Disciplined Life (1962), p. 23
