Mountains teach humility. Even the humble mountains that everyone’s climbed, like Virginia’s Old Rag, teach that humility. That as fast as you go, the way isn’t quick. That as decent as your sense of direction may be, you have to give up knowing where exactly you are. That however even moderate heights thump your heart, your fear is irrelevant to the situation. That as much as you curse at the mountain, the rocks aren’t moving. That as far as you have come, you still have a long way to go.
