I say that whoever claims to have finished a canvas is terribly arrogant.
It is difficult to stop in time because one gets carried away. But I have that strength; it is the only strength I have.
While adding the finishing touches to a painting might appear insignificant, it is much harder to do than one might suppose...
I'm never finished with my paintings; the further I get, the more I seek the impossible and the more powerless I feel.
