Chekhov never published an autobiography, but he did once write a letter in which, in Chekhovian fashion, he summed up his life in a paragraph. At The Paris Review Daily, you can read the Constance Garnett translation of this letter in full. You could also check out Brendan Mathews on reading Chekhov for self-improvement.
Remember the Muppet movie when Kermit has an existential crisis about time? Yeah, we never saw that one either. But a new biography of Jim Henson, Jim Henson: The Biography by Brian Jay Jones, discusses Henson’s early experimental filmmaking (sans puppets) and plans to open a psychedelic nightclub in the 1960s. You can watch the aforementioned trippy short film “Time Piece.”
