So could we think that some of the best writers of all times wrote their works under the effects of sadness?
I also think that sadness brings a very sweet and strong sensibility to describe some facts of life.
Thanks for your considerations, I really appreciate them.
Most definitely yes. It's an essential human emotion, I don't think books, painting, music would be so great without it. "An artists job is to comfort the uncomfortable..." I don't think they could do that without knowing first hand what suffering is.
