I follow rules I set for myself. Here are some examples:
· no dynamic steps on snow atop boulders;
· no dynamic steps in darkness on boulder fields;
· abandon any sense of urgency while traveling while dark;
· run all trail sections while light;
· take full deep breathes, never breathe shallower/quicker than 3-step tempo;
· commence work to extinguish a stress as soon as I notice its burden;
· never count down: how I feel now is how I’ll feel forever, but with greater challenges;
· the moment my mood turns down, look around, find beauty, use and watch my mind;
· when scrambling while dark and sleep-deprived, assess if I can trust my risk-assessment;
· switch breathing tempo when switching among running, jogging, scrambling, walking, pausing; · sleep as soon as possible after stopping to do so.
