Yes, you can. I remember those Xmas lights... Now I work then out together with my daughter. I can finally enjoy the process of decorating the tree with those I love and witnessing the joy it brings my children instead if seeing the unhappiness in others who don't know how to find their joy in the meaningful things of life.
I think art is often born of heaviness. Perhaps it is the release of it. But I have never met an artist who does not feel things deeply; who does not feel the heaviness of the world. They have no choice but to let some of it out - to scream it out in rhythm and rhyme and in colour and frames.
