Reference is very important.
Our mind flashes straight to writing when reference is mentioned but it can be useful in other areas as well.
Take an example of a worker who is fulfilled in her work, consults for others successfully. At the end of the day, she barely does advertising but her work speaks for her. Most of her clients are responsible for promoting her business, not because she asked them to. They saw value in her work, and I am sure others saw it too.
So, her customers made huge reference about her business. And the referred also brought in people, and the process keeps going.
Her brand basically run on references, she barely does advertising. And now, she doesn't need advertising. Reference can be powerful, it leads directly to the source.
