He was very self critical so he refused to publish most of his work, but he was still published and acknowledged during his lifetime although not with the world fame he has now, other famous German speaking authors mention and acknowledge his work during the 20s. Also he died very young, so most of his work was unfinished.

Some argue that, after he wrote "The judgement" in just 8 hours one night, a fiery explosion of creativity and geniality, he was often disillusioned with the slow and exhausting progress most of his other work made.

A lot of his work was unpublished and unfinished until his friend Max Brod published it posthumously against his wishes.

That he died penniless can be described as an exaggeration, he was very successful in his daytime job, although he was not fond of it. But he never managed to earn a living as a writer, so much is true.
