If you cannot bear the silence and the darkness, do not go there; if you dislike black night and yawning chasms, never make them your profession. If you fear the sound of water hurrying through crevices toward unknown and mysterious destinations, do not consider it. Seek out the sunshine. It is a simple prescription. Avoid the darkness.
