Honoré De Balzac said this quote

“ If the artist does not fling himself, without reflecting, into his work, as Curtis flung himself into the yawning gulf, as the soldier flings himself into the enemy's trenches, and if, once in this crater, he does not work like a miner on whom the walls of his gallery have fallen in; if he contemplates difficulties instead of overcoming them one by one ... he is simply looking on at the suicide of his own talent. ”
