About a decade ago I randomly picked up One More Thing by BJ Novak, which was hilarious and got me into the form of short stories. I immediately Googled something like "best short story writer" and was introduced to Anton Chekhov, which was the second collection I read, and a pretty funny leap from one to another in retrospect.

Since then I've read countless stories and collections. I'm always reading a novel or two as well, but short fiction is my favorite.
