The question is how to go about writing characters who aren't like you, not whether you are allowed to.
Right now, while we're still in the midst of NaNo and can observe it directly rather than in hindsight, is a great time to write down some thoughts about how it's going and what you can learn from it.
It's challenging to have the desire to create works that cause minimal harm, paired with the certain knowledge that our writing incorporates our ignorance and erroneous beliefs.
Looking like a finished work isn't what a first draft is for. It's a tool to help you tell the story.
I'm chuffed that my hero and role model Captain Awkward was kind enough to link to Story Hospital from today's post. If you're coming over from that post, welcome!
Every single approach to writing is perfectly okay, as long as it's in line with the kind of writer you want to be.
It's very easy, in this atmosphere focused on numbers and "winning," to get jealous, and anxious, and insecure.
When the business and practical elements of publishing demand your attention, always come back to story; it's the one thing you can't outsource.
You are making a commitment to yourself to get some writing done. Take it seriously and defend it fiercely.
