I dictate it.
Many of the authors I work with are concerned about whether or not their typing, spelling and grammar skills will get them through a 70,000 word book. It just doesn’t matter. “Writing” doesn’t have to mean writing.
The surest way to get your book or blog post finished is to use the method that’s easiest for you. If you type a thousand words a minute like Best Beloved does, you should type — if you enjoy it. If you prefer scribbling longhand in a notebook, do it. The extra step of having your work transcribed, whether by you or someone else, will probably take less time than struggling to use tools and methods that feel unnatural to you. Even if that’s not the case, using tools and methods that make you struggle diminishes your art.
When Best Beloved was too ill to work with me, writing was excruciating. I’ve been a writer and a coder most of my life. Just because I type 50 wpm doesn’t mean I like it.
