Useful, but not universal. Efficiency is not the point of storytelling. Some details might not appear to have led anywhere in the story, but could have been there for texture, subtext or symbolism.<p>Chekhov's minimal, efficient, realist style is unique to him and complements his tone and content, but it's not a necessary condition for good writing.
