Some people when they have taken too much and have been driven beyond the point of endurance, simply crumble and give up. There are others, though they are not many, who will for some reason always be unconquerable. You meet them in time of war and also in time of peace. They have an indomitable spirit and nothing, neither pain nor torture nor threat of death, will cause them to give up.
Roald DahlWhen you're writing a book, it's rather like going on a very long walk, across valleys and mountains and things [...] The highest mountain on the walk is obviously the end of the book, because it's got to be the best view of all, when everything comes together and you can look back and see that everything you've done all ties up. But it's a very, very long, slow process.
