As artists we are often told to specialize. I think some of that comes from the advantage of mastering one technique at a time. In sales, specializing or focusing your product line is also key. However, the opposite option is not as often discussed, but is equally as valid—that of the generalist.
The generalist is an artist who approaches art like a science, a series of skills to be mastered, based on a foundation of art history, and with the ability to transition into any chosen field within the wider art market. Ron Lemen is one artist that comes to mind who has chosen this path.
