None. But then, that's still more than OP was able to adduce, as they provided no examples at all, neither groundbreaking nor creative. Which is my point: the bar of 'an anecdote' is so very low. You can provide a anecdote for the creative value of smelling rotten apples in a drawer (Schiller); you can provide an anecdote for the creative value of drinking 50 coffees a day (Balzac); you can provide an anecdote for countless crazy things people have done! But you can't provide an anecdote about reading obituaries?
