“Is there actually a word for this kind of inner conflict that overcomes you when you plan to go on a longer journey, but still have the possibility not to do it? The spirit seems to split in two parts: A courageous and youthful part of the brain that boldly, curiously and adventuresomely wants to break out of familiar conditions. And a risk-averse, convenient and matured part, that would rather anxiously stick to the familiar surroundings. But shortly after I decided to name this self-conscious wanderlust ‘Invakanz’ it disappeared with every step in fresh air like a slight headache.” (Walter Moers: The Labyrinth of Dreaming Books)
