What is the important thing of growth sales, 1. Friendly Appearance, 2. Relationship, 3. Behavior, 4. Talent or good product?

it is the relationship because that is the most important of all in business ,a good relationship to a customers,co workers, and superiors....on that point there's  have a unity and fairness of the business ..

For me behavior, because with right attitude you can build a good relationship and appearance can go along with it with proper grooming and attire. While talent or good product wouldn't be enough without the good behavior.
