What is the one thing your MC wants more than anything? If you're like me you're answer will resemble an onion. The first layer will seem easy, but you'll soon realize it's not the one thing - there are several things your MC wants. You need to dig down and find out which are red herrings (or really just different manifestations of the same desire) and which is the real deal. You peel back layers until you get to the heart of the thing. My onion looked like this:
What does Mop want most?
To find out who she is.
That's what Mop really wants when she decides to use her talent to help Mr. Blank find Daisy's killer. She knows she's not like everyone else and this might be the only chance she has to find out what she is like - and if there's anyone else like her.
OKAY! We're getting somewhere. Oh. Wait. Mr. Maass has some additional work for us.
Write down the opposite of what your MC wants. Why, Donald, why? I thought we were friends!
Here's the deal. The opposite of what your MC wants most can absolutely (and probably should) be something they also want. In Mop's case, the opposite of finding out who she is, is the safest bet - forgetting about who she really is. Keeping the status quo. Not to go looking for answers. It's a powerful desire, especially as she comes to understand that finding out the truth about herself will endanger her mother, her friends and herself (of course) but it will also endanger her fragile sense of self. She might not be strong enough to handle the truth. Who wouldn't have a strong desire to run and hide? Thus, inner conflict.
So, how do you create inner conflict in your characters?
