Matisse

. . I have always sought to be understood and, while I was taken to task by critics or colleagues, I thought they were right, assuming I had not been clear enough to be understood. This assumption allowed me to work my whole life without hatred and even without bitterness toward criticism, regardless of its source. I counted solely on the clarity of expression of my work to gain my ends. Hatred, rancor, and the spirit of vengeance are useless baggage to the artist. His road is difficult enough for him to cleanse his soul of everything which could make it more so.
Henri Matisse

Creativity takes courage.
