Not only is perfectionism's "disciplined" approach unnecessary -- it is actively destructive. It makes beginners feel like they aren´t good enough and experts feel like they are never, ever finished. It is the worst.
The concept of perfectionism is Puritanical and ludicrous -- it presupposes that all we do in the name of "discipline" (a joyless activity) has a positive effect on creative output.
The truth is quite the opposite. The destructive consequences of this all-too-prevalent attitude in the western world is so extreme that it can destroy the confidence of its practitioners.
I wish that all the kids in the West and, why not, the world, would decide to rebel against their parents at the exact same instant. And in that moment, all the war and prejudice in the old world would be gone.
It would be a collective decision to unite in the name of rock n' roll, or some other high ideal.
"... the kids from Brooklyn to Tehran fell into the same silence / as the kids out West with TV sets stopped to listen for a moment / a new world was born . . ."
