I honestly don't think you can. You just need to work on a world/story that interests you and make it the best you can.
I have spent years writing about and creating new worlds for my characters to play in. Each time it was fun, each time I learned more about the craft of story telling. Now I write stories that are based in our world, because I have found that interests me more. (Will it interest others only time will tell.) I am still creating a world of sorts, it is ours through a lenses, darkly.
