Johann Wolfgang Von Goethe said this quote

...nothing is more dangerous than solitude: there our imagination, always disposed to rise, taking a new flight on the wings of fancy, pictures to us a chain of beings of whom we seem the most inferior. All things appear greater than they really are, and all seem superior to us. This operation of the mind is quite natural: we so continually feel our own imperfections, and fancy we perceive in others the qualities we do not possess, attributing to them also all that we enjoy ourselves, that by this process we form the idea of a perfect, happy man,—a man, however, who only exists in our own imagination.
