The Healthy Writer by Joanna Penn and Dr. Euan Lawson
I found several helpful tips for being, not just a healthy writer, but a healthy person. This is a resource to go back to for motivation and advice throughout life. I would argue that anyone with a sedentary occupation would benefit from the recommendations within this book. I gave it four stars only because some of the suggestions were ones I would not apply personally. But, modifications can be made with any form of habit-building, which makes this book a great place to start.
