I do a lot of research before starting my manuscripts, but that doesn't stop me from stumbling over gaps in my knowledge while I'm in rough draft stage. Rather than letting them slow me down, I write bolded, all-caps notes to myself and keep going. My current work-in-progress's notes include:
LOOK UP APPROPRIATE DISHES FOR WINTER DINNER.
CONFIRM DETAILS OF BATTLE OF QUEENSTON HEIGHTS.
PRETEND YOU'RE INTERESTED IN SHEEP AND ADD SOME DESCRIPTIVE DETAIL HERE.
The funny thing is, by the time I've learned enough about sheep to flesh out that paragraph, I bet I'll think sheep are fascinating. Maybe even almost as interesting as horses.
That's how it usually works for me. Before I started researching the War of 1812 as part of my current hero's backstory, I would've said it was nowhere near as interesting as the Napoleonic Wars. Now that I know more about it, well, it's messy and gripping and horrible, and it's just criminal how boring my high school history class made it sound.
Since I started writing historical romance, I've developed surprising interests in the flora and fauna of islands of the Indian Ocean (one of these days I'll finish that shipwreck story), the duties of footmen (I once had a hero go undercover as a servant, then decided it didn't work and rewrote those chapters), and the workings of the East India Company fleet. To name only a few. And my conclusion is that almost nothing is boring once you start to learn about it. Really, I think this Discovery Channel ad from a few years back sums up my attitude toward just about anything I've ever needed to research:
What about you? What topics that you thought were boring turned fascinating as soon as you knew anything about them?
