In addition to writing the music and drama mentioned in the article, Satie also wrote about his own (rather eccentric) life. An excerpt about optimizing that stood out to me:

> An artist must regulate his life. Here is a time-table of my daily acts. I rise at 7.18; am inspired from 10.23 to 11.47. I lunch at 12.11 and leave the table at 12.14. A healthy ride on horse-back round my domain follows from 1.19 pm to 2.53 pm. Another bout of inspiration from 3.12 to 4.7 pm. ... My only nourishment consists of food that is white: eggs, sugar, shredded bones, the fat of dead animals, veal, salt, coco-nuts, chicken cooked in white water, mouldy fruit, rice, turnips, sausages in camphor, pastry, cheese (white varieties), cotton salad, and certain kinds of fish (without their skin).
