Success is subjective. For some, success is their income, for others it is the size of their house, for some it is what car they own, for some it is what kind of family life they have, for some it could be how happy they feel on a daily basis (basically if they are happy or not), etc. Success for a person may depend on their dreams and goals.
For a Business, success could be either maximizing profits, or maximizing sales, or maximizing customer satisfaction, or maximizing shareholder/owner satisfaction, or maximizing employee satisfaction, etc. Success for a Business depends on its corporate objectives.
