The artistic temperament is a disease that affects amateurs. Artists of a large and wholesome vitality get rid of their art easily, as they breathe easily or perspire easily. But in artists of less force, the thing becomes a pressure, and produces a definite pain, which is called the artistic temperament.
Gilbert K. ChestertonA man cannot have the energy to produce good art without having the energy to wish to pass beyond it.
Gilbert K. Chesterton
