Subverting habits means replacing habits. What I’ve learned from my walks is that every day — every step — on the road is a chance for self-renewal, to cast off some small micron of a past, shittier, scared, low-self-worth, less-kind self, and replace it with a more patient, more empathetic, higher value bizarro self. Someone you could have been earlier in life, given a different set of circumstances. Micron by micron, atom by atom, it adds up (one hopes!).
