January 20: The end of writing. When will it take me up again?
January 29: Again tried to write, virtually useless.
January 30: The old incapacity. Interrupted my writing for barely ten days and already cast out. Once again prodigious efforts stand before me. You have to dive down, as it were, and sink more rapidly than that which sinks in advance of you.
February 7: Complete standstill. Unending torments.
March 11: How time flies; another ten days and I have achieved nothing.
