Simone De Beauvoir said this quote

A normal existence - what could be more irrational? It's fantastic the number of things you're forced not to think about in order to go from one end of the day to the other without jumping the track! And the number of memories that have to be driven from your mind, and truths that have to be evaded! That's why I'm afraid to leave,' I said to myself. In Paris, near Robert, I manage without too much difficulty to avoid the traps; I carefully mark them, and there are alarm bells to warn me of dangers. But alone, under an unknown sky, what would happen to me? What truths would come suddenly to blind me? What chasms would open before me? Oh yes, chasms close, truths fade out - that is sure and certain; I've seen it happen often enough before. We're like those earthworms one vainly cuts in two, or those lobsters whose legs grow back again. But the moment of false agony, the moment you'd rather die than mend yourself once again - when I think of it, I lose heart. I try to reason with myself: 'Why should anything happen to me? But why shouldn't anything happen to me?' It's never safe to go off the beaten path. It's true, I feel a little stifled here, but you get used to being stifled. And a habit is never bad, despite what they say.
