Visionary  A visionary is a person with a clear, distinctive and specific (in some details) vision of the future, usually connected with advances in technology or political arrangements. Examples would be Buckminster Fuller in architecture, and some of the pioneers of personal computing such as Steve Jobs. A visionary may function as a secular prophet, emphasising communication and a figurehead role, rather than implementation.
Marketing  Marketing, as suggested by the American Marketing Association, is "an organizational function and a set of processes for creating, communicating and delivering value to customers and for managing customer relationships in ways that benefit the organization and its stakeholders".In order to be successful in the marketing world, you must possess two key qualities: patience and consistancy.

Marketing-"taking actions to define, create, grow, develop, maintain, defend and own markets".

Planning   In most organizations `strategic planning' is an annual process, typically covering just the year ahead. Occasionally, a few organizations may look at a practical plan which stretches three or more years ahead.

To be most effective, the plan has to be formalized, usually in written form, as a formal `marketing plan'. The essence of the process is that it moves from the general to the specific; from the overall objectives of the organization down to the individual action plan for a part of one marketing programme. It is also an iterative process, so that the draft output of each stage is checked to see what impact it has on the earlier stages - and is amended accordingly
