Haruki Murakami said this quote

It might be a little silly for someone getting to be my age to put this into words, but I just want to make sure I get the facts down clearly : I'm the kind of person who likes to be by himself. To put a finer point on it, I'm the type of person who doesn't find it painful to be alone. I find spending an hour or two everyday running alone, not speaking to anyone as well as four of five hours at my desk, to be neither difficult or boring.
