What kind of story-You Ask?
Ask yourself questions like "How Did I Get Here?", or "What specific event made me who I am today?"
Perhaps you had a defining moment when the light bulb clicked. Relate that story to your marketing piece.

If you have a mobile business, you can share the reason you decided to choose the type of food that you are serving.
For instance, you love authentic Mexican food, but, in your area, there is no place to get good, authentic Mexican food-so you decided to start your own business offering the best authentic Mexican food they have ever tasted. You can follow up with a story about where your recipes come from (great-grandmother, famous uncle, i.e.) and what makes it so special.

If you have a catering business, you can talk about what made you take the leap into this type of business. As a Personal Chef, you can share how you grew up cooking food for your family and extended family and then friends. As a cookbook author, you can share where your recipes came from, how long you've had them, and why you want to share them with your reader.

I'm sure you get the idea of where to get information for your story. If you're not good at writing, find a friend or business associate that has good copywriting skills to write it for you. Another good way to get your story is to stage an interview. In this case, someone interviews you – whether by audio or a written interview. You can then publish this interview on your website or use elements of the interview to form your story for print marketing materials.
