I managed to get my hands on a copy of Hidden Immigrants by Linda Bell. Just leafing through it I came upon this paragraph. It describes me at the moment. Working away.

I basically left home when I was 16 by going to boarding school. From a very young age I traveled a lot by myself. That was good. But it prepared me to deal with loneliness too, and do things on my own. But that can be good. For instance, writing a book is a very lonely experience.
