The ability to produce strong writing is as much about your mental and physical health as it is your dedication to the work. If you aren't taking care of yourself, the likelihood of completing multiple drafts of a 60,000+ word story is pretty slim. If you start to feel overwhelmed and overworked, take some time to decompress and relax. When you feel balance returning, get back to work.
Every Wednesday, as I draft my second novel, I will be posting writing tips, advice, and tough love reminders for myself and anyone who may need it. Feel free to share your own.
