“The scientist has the habit of science; the artist, the habit of art.”

“I realized very soon the danger of repeating indiscriminately (forms of) expression... for the spectator even more than for the artist, art is a habit forming drug and I wanted to protect my (art) against such contamination.”

“How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.”

“One hasn't become a writer until one has distilled writing intoa habit, and that habit has been forced into an obsession.Writing has to be an obsession. It has to be something as organic,physiological and psychological as speaking or sleeping or eating.”

“Love has a nasty habit of disappearing overnight.”

“Habits form and habits grow, Then some time later, habits go.”
