The success that comes from my books is not something I feel very comfortable with. Past a certain point you have to accept the idea that the success is a lot to do with the timing and luck and that divorces you from it massively. There are aspects of it that I haven't got used to at all. But I've enjoyed some parts of it massively. It relates to the same reason I did a lot of backpacking — partly for the experience — it's something to tell my grandkids. It's a weird chain of events to have in your life.
