Walking marathon

An hour and a half of walking in one direction is the distance at which the city and your head start looking different.

Ten thousand steps in one go is roughly seven kilometres and an hour and a half, so put it in the day in advance. Pick a one-way route so there's no temptation to turn home halfway: the next neighbourhood, along the water, the last stop on the line. Take water and headphones, but walk the first twenty minutes in silence. Hold a steady pace where you could talk but not sing. Count the steps with your phone or watch, otherwise the argument with yourself never closes. Take transport back, the task was to walk it, not to survive it.

What do I think about when there's finally nothing to keep me busy?
