Seth Godin in the April 2006 issue of Ode magazine:
How to tell a great story

A couple of my favorites:

Great stories are subtle. Surprisingly, the fewer details a marketer spells out, the more powerful the story becomes. Talented marketers understand that allowing people to draw their own conclusions is far more effective than announcing the punch line.

Great stories are rarely aimed at everyone. Average people are good at ignoring you. Average people have too many different points of view about life and average people are by and large satisfied. If you need to water down your story to appeal to everyone, it will appeal to no one. The most effective stories match the world view of a tiny audience—and then that tiny audience spreads the story.
