What's the difference between Worldbuilding and storytelling?

I've been struggling with this concept the past few days. I'd like to think I excel in worldbuilding, but I don't think I excel in storytelling. Ultimately, my end goal is to create stories for the various worlds I've built. But how do you separate Worldbuilding from storytelling to such a degree that you can singularly focus on honing your storytelling skills? <br><br>For example I'll tell you that my world is Earth 1981. I can answer questions like "What's the name of the largest city in North America? What's the name of the largest city in South America?" I'd then give you an answer like "New York City" or "Rio de Janeiro" I feel that this sets up the framework of a world you can then start to build a story on top of. But I'm unsure of how much worldbuilding I end up doing while creating the story itself, and how much worldbuilding I'm doing to build the world itself.<br><br>I've also thought about it in the terms of role playing games. In tabletop games like Dungeons and Dragons a worldbuilder takes the place of a game master. He builds a world, populates it with people and creatures, creates story hooks and NPC's. He also controls the environment, the weather, the outcome of the players actions. He has a general idea of how he wants his story to play out, and he controls a lot of factors that influence the outcome of the story, all while the players control a single character. How much worldbuilding is the GM doing? How much storytelling is he doing? The answer I'd think is pretty much everything. He's controlling the world, the story, the environment, and the characters. He's writing the story, he's also building the world. While writing a story though it's easier to separate the two processes. You're only controlling the story. Your characters can and will do their own thing. But ultimately you are writing their actions and controlling their outcome.<br><br>I'm sort of looking for a way to compartmentalize my world building and my storytelling so that I can focus on one or the other. Does that make sense? I don't want to be able to build a structure, I want to be able to build a house, and then separately live inside of it.<br><br>What's the difference between Worldbuilding and Storytelling? How do you make that distinction?
