Time. Everything takes longer than I think it will, more drafts than I think it will. Then there’s the business and admin side of things that eats up so much free time. Then the joy of reading and supporting other people’s work. I also work a more-than-full-time job that’s entirely separate from my writing, as well as taking on smaller writing-type/teaching jobs from time to time. I function best when busiest, but I have a partner and family and friends I love so much, and I want to offer help and support to them, and I can’t really fathom turning them down in favor of writing most of the time.
