It's not curators, it's not critics, it's not the public, it's not collectors who find great artists - it's other artists.

Experimental artists build their skills gradually over the course of their careers, improving their work slowly over long periods. These artists are perfectionists and are typically plagued by frustration at their inability to achieve their goals.

Titian and Rembrandt, Monet and Rodin, Frank Lloyd Wright and Le Corbusier, Mark Twain and Henry James, Robert Frost and Elizabeth Bishop, to name a few. Twain wrote 'Tom Sawyer' at 41 and bettered it with 'Huckleberry Finn' at 50; Wright completed Fallingwater at 72 and worked on the Guggenheim Museum until his death at 91.

There are two very different types of artists: those I call Old Masters, who work by trial and error and tend to improve with age, and conceptual people, or Young Geniuses, who generally do their best work early in their careers.

Important artists are innovators whose work changes the practices of their successors.

It's not curators, it's not critics, it's not the public, it's not collectors who find great artists - it's other artists.

The precision of their goals allows conceptual artists to be satisfied that they have produced one or more works that achieve a particular purpose... a problem solved can free him to pursue new goals.
