Whatever the challenges of the day, it is so easy. It is simple: about walking, about moving one foot after the other, about a rucksack in place, about pacing oneself on the path, about an action to be done. But evening… whatever the easiness of the evening, it can be a challenge. The absence of tasks, the absence of actions to fill the mind, the role is unclear, the visibility may disappear with the night, and still that’s when the mind is on its own that evolution really happens!
