Step 1: Understanding the Concept:
The question asks to identify the term that best describes work which is intrinsically satisfying.
Step 2: Detailed Explanation:
Let's analyze the different connotations of work:
Livelihood: Work viewed primarily as a means of earning money to support one's life. The satisfaction is external (the income).
Job: A specific set of tasks performed in exchange for pay. The focus is on the employment contract and remuneration.
Career: A long-term professional journey, often involving advancement, promotion, and increasing responsibility. The focus is on progress and achievement.
Calling: Work that a person feels deeply connected to and passionate about. The satisfaction comes from the work itself—its purpose, meaning, and the act of doing it. It is seen as an integral part of one's identity.
Step 3: Final Answer:
The phrase "deriving satisfaction from work itself" perfectly matches the definition of a calling, where the work is an end in itself, not just a means to an end.
