I have to remind myself to switch off and just go out and hit the trail and do some unscheduled and unstructured exploring. The oodles of writings and podcasts and music and media at my fingertips are quite wonderful, and have really enriched the depth and breadth of my inner life, but then what you consume tends to fill up your sensory range and direct your thoughts. You never know what you'll start thinking about and feeling just wandering around.
