"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. I think in my own way I'm aware of this danger - probably through experience - and that's why I've had to constantly keep my body in motion, in some cases pushing myself to the limit, in order to heal the loneliness I feel inside and to put it in perspective. Not so much as an intentional act, but as an instinctive reaction." (#23 p20)
