What seems to sell books is good word-of-mouth, not promotion tours. I'm too old to believe that media promotion of a book really matters. What matters is how it will look 100 years from now, not how many copies are sold.
John UpdikeWe're past the age of heroes and hero kings. ... Most of our lives are basically mundane and dull, and it's up to the writer to find ways to make them interesting.
John UpdikeWriting fiction is like music. You have to keep it moving. You can have slow movements but there has to be a sense of momentum, of going someplace. You hear a snatch of Beethoven and it has a sense of momentum that is unmistakably his. That's a nice quality if you can do it in fiction.
