"You live like this, sheltered, in a delicate world, and you believe you are living. Then you read a book (Lady Chatterley, for instance), or you take a trip, or you talk with Richard, and you discover that you are not living, that you are hibernating. The symptoms of hibernation are easily detectable: first, restlessness. The second symptom (when hibernating becomes dangerous and might degenerate into death): absence of pleasure. That is all. It appears like an innocuous illness. Monotony, boredom, death. Millions live like this (or die like this) without knowing it. They work in offices. They drive a car. They picnic with their families. They raise children.
And then some shock treatment takes place, a person, a book, a song, and it awakens them and saves them from death."
Anais Nin, Diary, Winter 1931-1932
