I understand that many people's success relies on interpersonal relationships, but no great success can be achieved solely because of relationships. There is a concept here called Dunbar's number: 150. It means that a person can maintain good relationships with roughly 150 people at most. However, no great enterprise can achieve greatness solely by relying on the leader's 150 good relationships; it must gain the support of more strangers to become great. This requires the use of scientific management and operational models, scientific decision-making, scientific products, and so on. But the essence of science is knowledge. Therefore, those who achieve success solely through interpersonal relationships, if they disdain knowledge as a result, will never achieve great success.
