Naturally one would rather be a broad artist with power to evoke beauty from every phase of experience--but when one unmistakably isn't such an artist, there's no sense in bluffing and faking and pretending that one is.
Warhol came from an ordinary family and he had a profound understanding about capitalism and material culture. He was probably one of the few Western artists - or artists from the United States - that could be considered a true product of his time and brought out that kind of spirit of the culture.
You are right in demanding that an artist approach his work consciously, but you are confusing two concepts: the solution of a problem and the correct formulation of a problem. Only the second is required of the artist.
Some artists leave remarkable things which, a 100 years later, don't work at all. I have left my mark; my work is hung in museums, but maybe one day the Tate Gallery or the other museums will banish me to the cellar... you never know.
While one should always study the method of a great artist, one should never imitate his manner. The manner of an artist is essentially individual, the method of an artist is absolutely universal. The first personality, which no one should copy.
If you are a cabaret artist and you are mostly singing other people's songs, you're asking them to rethink a song, listen to it in a different way. The most impact you can have while asking them to re-listen to a song is if it's a song they know very well.
Whenever the truth is uncovered, the artist will always cling with rapt gaze to what still remains covering even after such uncovering; but the theoretical man enjoys and finds satisfaction in the discarded covering and finds the highest object of his pleasure in the process of an ever happy uncovering that succeeds through his own efforts.
Of what use is the universe? What is the practical application of a million galaxies? Yet just because it has no use, it has a use - which may sound like a paradox, but is not. What, for instance, is the use of playing music? If you play to make money, to outdo some other artist, to be a person of culture, or to improve your mind, you are not really playing - for your mind is not on the music. You don't swing. When you come to think of it, playing or listening to music is a pure luxury, an addiction, a waste of valuable time and money for nothing more than making elaborate patterns of sound.
