An artist cannot fail. It is a success just to be one.

I have not lost faith. I'm not in despair, because I know that there is a moral order. I haven't lost faith, because the arc of the moral universe is long, but it bends toward justice.

What do Drawing Singing Dancing Music Making Handwriting Playing Story writing Acting Remembering and even Dreaming all have in common? They come about when a certain person in a certain place in a certain time arranges certain uncertainties into certain form.

Of course, one never knows what's going to come out, but as soon as the drawing gets underway, a story or an idea is born, and that's it. I spend hour after hour while I draw, observing my creatures and thinking about the mad things they're up to, basically, it's my way of writing fiction.

I’m a little taken aback by anyone calling himself an artist because of my feeling that that’s the kind of designation that other people should give. You can be an artist in any field, but getting a degree to call yourself an artist would be like getting a diploma to call yourself a genius. If your work is good enough, it can be art, but art isn’t a product. It’s a quality. Sometimes that’s lost sight of. Quality can be in anything.

I was screened a bit, but it was far out. I should have had a better look at it. I just kind of lost it a sea of red there . . . because we’re not used to playing in a building like that.

But the point yet remains that the means to the end are just that. Art (and life) may be about the journey, but if the endpoint doesn't grab someone's attention, they aren't likely to ask you how you did it.
Ramie Leigh
++++++++++++++
It seems to me that today if you want to produce art seriously and make for yourself a little corner of originality, or at least keep for yourself a thoroughly guiltless personality, you must immerse yourself in solitude. There is too much tittle-tattle. [Il y a trop de cancans.] It's as if pictures were being painted by stock exchange players, by friction from people avid for profits. Apparently you are supposed to rely on the mind and the ideas of your neighbor in order to do anything at all, much as a businessman requires the capital of other people in order to earn a sou. All these transactions put your mind on edge and falsify your judgment.
The 22-year-old Ed Degas, Notebooks, 1856
++++++++++++++
I believe it is possible that, through horizontal and vertical lines constructed with awareness, but not with calculation, led by high intuition, and brought to harmony and rhythm, these basic forms of beauty, supplemented if necessary by other direct lines or curves, can become a work of art, as strong as it is true.

It may be a point of great pride to have a Van Gogh on the living room wall, but the prospects of having Van Gogh himself in the living room would put a great many devoted art lovers to rout.

I like to do something that I don’t exactly know how to do. I don’t like to do things that I know I can do. If I take a certain approach to certain paintings, when I finish the problem, I don’t have to go on with it. I’m more interested in finding what else I can do that’s more of a challenge for me.
Robert Ryman

The moment you know how to do certain things, you should by rights stop doing them. You would be ceasing to search and starting to perform. You would become your own expert, and your art will become an exercise in self-congratulation.

Unlike artifacts such as bows and arrows, language was not designed by people; people evolved so as to be able to have it, just as bats evolved so as to be able to echolocate and elephants evolved so as to be able to pick things up with their noses.

There is no pride in saying out loud: Me too, I'm a painter! Pride consists in saying softly to others: You neither, you aren't a painter.

Drawing is the activity of organizing [a piece of art] with line. A drawing starts with unordered blank paper. As each line is added the paper becomes more organized, until a final state of order is achieved and the drawing is complete.

Driftings in and out of the crowd

✱ The SKETCH HUNTER has delightful days of drifting about among people, in and out of the city, going anywhere, everywhere, stopping as long as he likes – no need to reach any point, moving in any direction following the call of interests. He moves through life as he finds it, not passing negligently the things he loves, but stopping to know them, and to note them down in the shorthand of his sketchbook, a box of oils with a few small panels, the fit of his pocket, or on his drawing pad. Like any hunter he hits or misses. He is looking for what he loves, he tries to capture it. It’s found anywhere, everywhere. Those who are not hunters do not see these things. The hunter is learning to see and to understand – to enjoy. [from The Art Spirit by Robert Henri. 1923]

Le Flânerie

✱ "The crowd is his domain, just as the air is the bird's, and water that of the fish. His passion and his profession is to merge with the crowd. For the perfect idler, for the passionate observer it becomes an immense source of enjoyment to establish his dwelling in the throng, in the ebb and flow, the bustle, the fleeting and the infinite. To be away from home and yet to feel at home anywhere; to see the world, to be at the very centre of the world, and yet to be unseen of the world, such are some of the minor pleasures of those independent, intense and impartial spirits, who do not lend themselves easily to linguistic definitions. The observer is a prince enjoying his incognito wherever he goes. The lover of life makes the whole world into his family,… just as the picture-lover lives in an enchanted world of dreams painted on canvas. Thus the lover of universal life moves into the crowd as though into an enormous reservoir of electricity. He, the lover of life, may also be compared to a mirror as vast as this crowd: to a kaleidoscope endowed with consciousness, which with every one of its movements presents a pattern of life, in all its multiplicity, and the flowing grace of all the elements that go to compose life. It is an ego athirst for the non-ego, and reflecting it at every moment in energies more vivid than life itself, always inconstant and fleeting." [from ‘The Painter in Modern Life’, Charles Baudelaire. 1863]
