There's nothing more physically exhausting than a sense of failure.

Das Werk lobt den Meister. (German: The work proves the craftsman.)

I think that all artists, regardless of degree of talent, are a painful, paradoxical combination of certainty and uncertainty, of arrogance and humility, constantly in need of reassurance, and yet with a stubborn streak of faith in their own validity no matter what.

We do not know and cannot tell when the spirit is with us. Great talent or small, it makes no difference. We are caught within our own skins, our own sensibilities; we never know if our technique has been adequate to the vision.

When we believe in the impossible, it becomes possible, and we can do all kinds of extraordinary things.

Only a fool is not afraid.

We need the rock of the past under our feet in order to spring forward into the future.
