In a beautiful letter to his sister-in-law, who was often bedridden, and depressed as a result, Kierkegaard wrote of the importance of walking. “Above all,” he told her in 1847, “do not lose your desire to walk: Every day I walk myself into a state of well-being and walk away from every illness; I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it.”
