Robert Henri said this quote

The object isn't to make art, it's to be in that wonderful state which makes art inevitable.

~ Robert Henri

All real works of art look as though they were done in joy.

~ Robert Henri

Lines are results, do not draw them for themselves. ... Lines give birth to lines. Drawing is not following a line on the model, it is drawing your sense of the thing. ... Make a drawing flow, stopping sometimes, and going on. ... Search for the simple constructive forces, line the lines of a suspension bridge. Get the few main lines and see what lines they call out. ... Have purpose in the places where lines stop.

~ Robert Henri

The work of the art student is no light matter. Few have the courage and stamina to see it through. You have to make up your mind to be alone in many ways. We like sympathy and we like to be in company. It is easier than going it alone. But alone one gets acquainted with himself, grows up and on, not stopping with the crowd. It costs to do this. If you succeed somewhat you may have to pay for it as well as enjoy it all your life.
