Marketing - When Is The BEST Time To Market Your Business

Marketing...Do you know who will buy your product or service and when they will? Is it possible it could be NEVER if we treat people disrespectfully? OR it could be today, in a month, in a year, in ten years if we treat people respectfully today? Does marketing include how we make people feel - every time we see them AND even if they don't want our product or service today?
