Of Human Bondage by William Somerset Maugham

Two months passed.

It seemed to Philip, brooding over these matters, that in the true painters, writers, musicians, there was a power which drove them to such complete absorption in their work as to make it inevitable for them to subordinate life to art. Succumbing to an influence they never realised, they were merely dupes of the instinct that possessed them, and life slipped through their fingers unlived. But he had a feeling that life was to be lived rather than portrayed, and he wanted to search out the various experiences of it and wring from each moment all the emotion that it offered. He made up his mind at length to take a certain step and abide by the result, and, having made up his mind, he determined to take the step at once. Luckily enough the next morning was one of Foinet's days, and he resolved to ask him point-blank whether it was worth his while to go on with the study of art. He had never forgotten the master's brutal advice to Fanny Price. It had been sound.
