"I can fairly be called an amateur because I do what I do, in the original sense of the word - for love, because I love it. On the other hand, I think that those of us who make our living writing history can also be called true professionals"

In this quote, David McCullough checks out the nuanced identities of both amateurs and specialists within the context of historic writing. He begins by addressing the term "amateur", often misconceived as a lack of skill or experience. McCullough welcomes readers to go back to the word's etymological roots, where "amateur" derives from the Latin "amator", implying "fan". He associates himself with this term due to the fact that he is driven by an enthusiasm for history. His pursuit of historic writing is sustained by authentic love, indicating that passion and enthusiasm are at the heart of his ventures.

McCullough contrasts this with the idea of a "expert", generally associated with proficiency, training, and the pursuit of a livelihood. He challenges a possible misconception that professionalism may do not have sentimentality or passion, verifying that professionals can likewise be deeply driven by love for their craft. In this light, professionalism is not merely transactional or duty-bound; it can be enriched by the same depth of dedication that defines amateurs.

This juxtaposition suggests that the boundaries in between amateur and professional requirement not be stiff or equally unique. McCullough eloquently argues that it is not just practical but commendable for one to embody both personas concurrently: an enthusiastic lover of a subject and a specialist who makes a living through it. This dual identity enhances the depth and breadth with which one engages in their field.

In essence, McCullough's quote motivates a reevaluation of how we perceive passion and know-how, urging us to value that professionals-- particularly in the arts and liberal arts-- frequently operate from a place of deep love for their subject matter. By acknowledging this intersection, we can redefine success and fulfillment, determining them not only by material gain however equally by the pleasure and satisfaction found in the work itself.
