Artistes

I only knew today that Ernest Hemingway committed suicide by putting a shotgun through his mouth. It's funny how writers, singers,poets, artists tend to have a depressive trait and many just kill themselves- Hemingway, Van Gogh, Virginia woolf... Do they need sadness as a muse in order to do what they do. Sometimes I feel this is kinda true.. It's so much harder to write a poem when you all jolly and golly. Sadness and creativity, do they go hand in hand?
