I love researching either what I'm writing about, or comparing too. I love learning, and that goes hand-in-hand with writing. Most of my research consists of history, language, and geography. I get as lost in my research as I do in my writing. It's swimming in an eternal ocean. There is so much to learn, and as a writer, infinitely more to expand on. Writing stories set in this world is a fun exploration, a kind of Socratic journey. But it's magnified when an entirely new world is created either by sheer inspiration for something new, or a parallel to something real.
Often times my kids inspire me to make certain adjustments or add new elements to create a unique environment or character. Many of my characters are inspired by them, adding a 'new set of eyes' to the creative process for elaboration.
I've gained an insane amount of knowledge researching for my works, and it was well worth it. How much research is too much? To me, the answer is that there is 'no too much'. What do you think?
