Short Stories in Science Fiction

I am an aspiring science fiction writer looking to create a career out of all the zany and obscure ideas that reside in my mind. While I write in other genres, I decided to create a blog specifically in science fiction to challenge me as a writer in two important ways: first, to write more in a genre that I always want to explore more, but gets sidetracked because it isn’t considered “realistic fiction” as oxymoronic as it should sound; the other, because I want to challenge myself to write more.  The pressure of having an audience (albeit nonexistent at this point) is enough to keep me writing and staving off writer’s block.
