An intriguing approach from Hugh Howey: take an idea (he’s mainly talking about SFinal ideas) and tell the story about how it’s broken. Not necessarily how it breaks, even, but how it’s already broken and it’s up to your character to deal with that.
Now, Howey writes dystopias, which is why I don’t read his stuff, and his approach is not the only way to generate a story from an idea. But it’s interesting.
