Books marketing has moved from the review culture to a preview culture.

Books should be both enlightening and entertaining.

While a lot of management development books try to teach you a lesson or give you a scenario of what corporate culture and work practices are about, they're theoretical and written in a sermonizing way. Most people don't get past the first chapter, and they just look nice on the bookshelf.

If a reader likes a particular author, they keep reading all his books, and if the supply is not kept up, then the reader shifts his loyalties.

I do not think I will ever write screenplays based on my books. I would not know what to cut out and what portions to keep. I like all the characters I have created. I cannot imagine chopping them off.

An author needs to be in the market. He or she needs to come out with a new book every year. That keeps you alive in the public mind and gives a push to your older books.
