In one of his best emotional intelligence books, Focus: The Hidden Driver of Excellence, Daniel Goleman advocates for systems science for us to understand how to relate to the world around us. According to this view, systems awareness will help each one of us to grasp the workings of an organisation, an economy or the global processes that support life under the sun.
Based on this theory, there are three ingredients to focus on: the inner self; others; and the outer world. These must work in a threesome for not only any leader to be successful but also for each individual who wishes to excel in life.
