" The world exists in you. Your experience of the world isn’t this objective unchangeable thing called ‘The World’. No. Your experience of the world is your interaction with it, your interpretation of it. To a certain degree we all make our own worlds. We read it in our own way. But also: we can, to a degree, choose what to read. We have to work out what about the world makes us feel sad or scared or confused or ill or calm or happy. "
