Passion is defined by the the Cambridge dictionary as “an extreme interest in or wish for doing something, such as a hobby, activity, etc”.
Excerpted from Finding Your Element: How to Discover Your Talents and Passions and Transform Your Life by Ken Robinson, the importance of having a passion for your occupation is elaborated. To begin with, it means that you are doing something for which you have a natural feel. It could be playing the guitar, or basketball, cooking food, or teaching, or working with technology or with animals. People in their Element may be teachers, designers, homemakers, entertainers, medics, firefighters, artists, social workers, accountants, administrators, librarians, foresters, soldiers. So an essential step in finding your Element is to understand your own aptitudes and what they really are.
