If you don't tell the story, others will make up a story about you and your business or product in their minds, and it might not be the story that serves you best. By documenting your story, you can look back and pick out the best parts of it, or have an expert and friends review and highlight what they believe the strongest parts of your story are. Sometimes you are too close to your story. A professional storyteller and branding expert can objectively leverage the most powerful elements of your story for the overall mission.
