Jean-Paul Sartre, Nausea

“This is what I thought: for the most banal even to become an adventure, you must (and this is enough) begin to recount it. This is what fools people: a man is always a teller of tales, he sees everything that happens to him through them; and he tries to live his own life as if he were telling a story.
But you have to choose: live or tell.” 

“I felt myself in a solitude so frightful that I contemplated suicide. What held me back was the idea that no one, absolutely no one, would be moved by my death, that I would be even more alone in death than in life.” 

“I do not think therefore I am a moustache”
