Henri-Robert-Marcel Duchamp (; French: [maʁsɛl dyʃɑ̃]; 28 July 1887 – 2 October 1968) was a French-American painter, sculptor, chess player, and writer whose work is associated with Cubism, conceptual art, and Dada, although he was careful about his use of the term Dada and was not directly associated with Dada groups. Duchamp is commonly regarded, along with Pablo Picasso and Henri Matisse, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting and sculpture. Duchamp has had an immense impact on twentieth-century and twenty first-century art; and he had a seminal influence on the development of conceptual art. By World War I, he had rejected the work of many of his fellow artists (such as Henri Matisse) as "retinal" art, intended only to please the eye. Instead, Duchamp wanted to use art to serve the mind.

The most solid advice . . . for a writer is this, I think: Try to learn to breathe deeply, really to taste food when you eat, and when you sleep, really to sleep. Try as much as possible to be wholly alive, with all your might, and when you laugh, laugh like hell, and when you get angry, get good and angry. Try to be alive. You will be dead soon enough.
Patience is a hard discipline. It is not just waiting until something happens over which we have no control: the arrival of the bus, the end of the rain, the return of a friend, the resolution of a conflict. Patience is not waiting passively until someone else does something. Patience asks us to live the moment to the fullest, to be completely present to the moment, to taste the here and now, to be where we are. When we are impatient, we try to get away from where we are. We behave as if the real thing will happen tomorrow, later, and somewhere else. Let's be patient and trust that the treasure we look for is hidden in the ground on which we stand.
