Søren Kierkegaard said this quote

“ By seeing the multitude of people around it, by being busied with all sorts of worldly affairs, by being wise to the ways of the world, such a person forgets himself, in a divine sense forgets his own name, dares not believe in himself, finds being himself too risky, finds it much easier and safer to be like the others, to become a copy, a number, along with the crowd. Now this form of despair goes practically unnoticed in the world. Precisely by losing oneself in this way, such a person gains all that is required for a flawless performance in everyday life, yes, for making a great success out of life. Here there is no dragging of the feet, no difficulty with his self and its infinitizing, he is ground smooth as a pebble, as exchangeable as a coin of the realm. Far from anyone thinking him to be in despair, he is just what a human being ought to be. Naturally, the world has generally no understanding of what is truly horrifying. ”
