On the cover
With a hectic schedule and deadlines looming, illustrator Mark Smith drew from his own anxiety for this issue's cover, a simple yet stark depiction of the emotion explored in our cover story. "I was trying to portray this feeling of a mind racing out of control," he says. "Any illustrator would know this feeling well, as a deadline gets closer and a concept still hasn't been found." Smith's work has been featured in The New Yorker, Harper's, Rolling Stone, Time, and elsewhere.
