Gustave Courbet Quote
.. there's nothing harder in the world than making art, particularly when no one understands it. Women want portraits without shadow, men want to be dressed up in their Sunday best; there's no way out. To earn money with things like that, you'd be better of walking on a treadmill. At least than you would not be abdicating your convictions.
In his letter (Paris, January 1846), as quoted in 'Gustave Courbet', by Georges Riat, Parkstone International, 2015
