"In certain areas of my life, I actively seek out solitude. Especially for someone in my line of work, solitude is, more or less, an inevitable circumstance. Sometimes, however, this sense of isolation, like acid spilling out of a bottle, can unconsciously eat away at a person’s heart and dissolve it. You could see it, too, as a kind of double-edged sword. It protects me, but at the same time steadily cuts away at me from the inside."
Haruki Murakami, What I talk About When I Talk About Running
