with me it is all, i need music to draw my comic, i need to read comics to draw my comic (when i get lazy, it usually gets me interested again) and i need to have a video playing to draw my comic (and honestly, to go to sleep too)
i just need something running to do anything since silence makes me feel uncomfortable
as for reading, if you were looking at more novels than comic books, my attention span is terrible, i cant pay attention to a novel, only novels i seem to be able to read are biographies on people i generally am interested in but eh...
