Gunsmith, my shop has a wall of technical manuals. I keep a notebook/sketchbook next to the bed for when I wake up with an answer to a design problem.
I just finished rereading Mysterious Island, working on the Hunger Games trilogy again now. After this, some more Zane Grey.
Those books are there so I can shut the mind off, escape for a few from things like the idiot I’m evicting, and perhaps gain a little perspective.
