Fantasy is escapism, but wait... Why is this wrong? What are you escaping from, and where are you escaping to? Is the story opening windows or slamming doors? The British author G.K. Chesterton summarized the role of fantasy very well. He said its purpose was to take the everyday, commonplace world and lift it up and turn it around and show it to us from a different perspective, so that once again we see it for the first time and realize how marvelous it is. Fantasy - the ability to envisage the world in many different ways - is one of the skills that make us human.
Terry PratchettBelief is one of the most powerful organic forces in the multiverse. It may not be able to move mountains, exactly. But it can create someone who can. People get exactly the wrong idea about belief. They think it works back to front. They think the sequence is, first object, then belief. In fact, it works the other way.
Terry PratchettIf you get the characters right you've done sometimes nearly half the work. I sometimes find I get the characters right then the characters will often help me write the book - not what they look like that's not very important - what people look like is not about their character. You have to describe the shape they leave in the world, how they react to things, what effect they have on people and you do that by telling their story.
