Artists and audiences
Here's a thought:
If an artist wants to be commercially successful, he has to learn to take the viewpoint of an audience.
For example, to a painter, a painting may be an experiment in lines and shapes. But to his customers, a painting is decoration for the home.
If he forgets his own viewpoint, he may become rich, but may also become unhappy because he feels he has never fully used his power. If he never remembers the audience's viewpoint, he may become self-satisfied, but poor and unhappy because almost nobody "understands him".
If he can successfully combine the two viewpoints, that's a great start.
