What is defined as the work done over a period of years in one area of interest?

A career is defined as the work done over a period of years in one area of interest. This long-term focus typically involves a series of jobs or positions within a chosen field, demonstrating a commitment to professional growth and development. It encompasses not just the specific roles held but also the skills, experiences, and advancements made throughout one's working life.

In contrast, an occupation refers to a broader category of jobs that may not necessarily reflect a long-term commitment to a specific field, while employment is a state of having a job rather than the progression or path within a profession. A job is more specific to a particular position or role held at a given time, usually temporary or focused on short-term responsibilities. A career, therefore, emphasizes the overarching journey one undertakes in their professional life, characterized by evolution and purpose within a specific area of interest.
