I’m a very positive thinker, and I think that is what helps me the most in difficult moments.

I prefer winter and fall, when you feel the bone structure of the landscape—the loneliness of it, the dead feeling of winter. Something waits beneath it, the whole story doesn’t show.

最难的事情是简单。

聪明人的快乐是我所知最罕见的东西。
