There is joy in a tightly focussed story, which explores a small number (one?) of characters, or a situation, or a single idea in depth. But those aren't the stories that make me want to rush out and write.And that immediately made me think of Cosmicomics [1965, 1968 in English] by Italo Calvino. It's a book of short stories, each based around a single piece of science, and I think they're the very definition of charming. They may not make me want to write, but they do make me want to hug myself happily and smile at strangers.
If you've never read Cosmicomics, I really think you should.
