Exploring.

Poortvliet, Hare in Thicket, 1966

When you give yourself to places, they give you yourself back; the more one comes to know them, the more one seeds them with the invisible crop of memories and associations that will be waiting for when you come back, while new places offer up new thoughts, new possibilities. Exploring the world is one the best ways of exploring the mind, and walking travels both terrains.

Rebecca Solnit, from Wanderlust: A History of Walking
