I am a professor up at Columbia, and I find the time to teach because I do love it. When art schools work, I believe it’s for the same reason they have ever worked. They work when they are places where artists can freely exchange ideas and information with great intensity and intimacy. They work when they are challenging environments that support radical experimentation within one’s own work—encouraging the acceptance of repeated creative failures, and the development of resilience to sustain making art for ages, way beyond school.
