I meant to mention yesterday that my "ideal" day varies based on my current priorities. At the moment, my "ideal" schedule focuses on a young-adult novel. When I'm not working on a novel or teaching, I may be focused on revising a picture book, writing a freelance article, preparing for a school visit, updating my website, etc.
I also devote regular time to honing my craft. I do this by reading and studying books on writing, and by attending writer's conferences and workshops. The craft book I'm currently reading is Plot & Structure by James Scott Bell. (Perhaps "honing our craft" would make a good topic for future blog posts?)
Thanks for all the feedback so far. I'm looking forward to reading what the other Teaching Authors have to say on this topic.
