Achieving the summit of a mountain was tangible, immutable, concrete. The incumbent hazards lent the activity a seriousness of purpose that was sorely missing from the rest of my life. I thrilled in the fresh perspective that came from the tipping the ordinary plane of existence on end.

The sea's only gifts are harsh blows, and occasionally the chance to feel strong. Now I don't know much about the sea, but I do know that that's the way it is here.

Facing the blind death stone alone, with nothing to help you but your hands and your own head.
