Here's my eternal struggle: finding that balance between the worldbuilding that is necessary for me to understand the world as a whole, and thus tell the story well, and the worldbuilding that is just me wasting time or procrastinating.
Part of that ties to the fact that I ended up doing a lot of worldbuilding well before I really got started with proper writing. My worldbuilding process for Maradaine was tied to the process of Learning How To Novel. And I definitely enjoy an in-depth worldbuild process. I'm fascinated by the idea of doing a deep, wide and thorough worldbuild without, necessarily, knowing what the novel is or is supposed to be. I like using that as a process of discovery.
Now, is that necessarily useful? Is it good for me to spend too much time worldbuilding. What does "too much" mean? I'm the wrong guy to answer that question, as I do adore going deep into the "too much".
Part of that is because, when I get stuck with the writing, I like to fiddle with maps. Thats a process that I find relaxing and engaging and creative, and let's me restore my juices and get back to the real writing work.
So, for some non-Maradaine projects, I'm trying to restrain myself to the worldbuilding I need for the story. We'll see if that works. It's a different kind of process, and I'm a little nervous about it, to be honest. So, we'll see.
But that does remind me, I've got some new maps to draw...
