Tim Berry has three stories your business strategy depends on. An excerpt:
Tell the story of an imagined best-possible customer wanting or needing something, finding your business, and buying from you. Try to describe that person (or company) in detail. Be able to describe the process in glorious detail. What did she want? What did he need? What led her to your business? What was he looking for? What problem did she have? How did he find your business, and what made him decide to buy? What were the important decision factors?
