The short story King. He began his career writing short stories for magazines while he worked as a copywriter at GM. He hated this job and used some themes from GM that he found to create satirical short stories. Many of them are quite dystopian and science fiction, which I don't normally like but there's a way Kurt Vonnegut writes that makes certain stories that wouldn't otherwise interest me totally enthralling. He's funny, satirical, provocative, and relatable in a lot of ways.
Go read it! Vonnegut isn't an author you've never heard of, but this is definitely something worth reading.
