For 17 years, as part of his daily writerly routine, the author and naturalist Mark Cocker has taken a two-mile walk down to the river from his cottage on the edge of the Norfolk Broads National Park. Over the course of those 10,000 daily paces he has learnt the art of patience to observe a butterfly, a bird, flower, bee, deer, otter or fly and to take pleasure in all the other inhabitants of his parish, no matter how seemingly insignificant. In turn these encounters have then been converted into literary epiphanies that are now a widely celebrated part of his work.
