Consider Thought-Fox as a poem about the process of creative writing.

"The Thought-Fox" provides a metaphorical glimpse into the act of writing—or, more precisely, one poet's struggle to write. The poem explicitly mentions the loneliness writing demands, and the late nights many writers spend slaving over their work, waiting for inspiration to strike, or obsessively exploring an idea. At the same time, "The Thought-Fox" also suggests that writing is innate and organic: while a specific image or event may inspire a first line, a poem ultimately comes from the dark forest of its poet's mind.
