In "The Penitent" by David Mamet, the character Charles reflects on the nature of professional work and the inherent disillusionment that often accompanies it. He conveys a sense of shame that comes from knowing that many professionals, including himself, may not contribute significantly despite being compensated for their efforts. This recognition highlights an underlying skepticism about the true value of the services they provide.

Charles suggests that much of professional work may revolve around the ability to maintain composure or a façade, rather than achieving substantial outcomes. This cynical perspective prompts readers to question the authenticity and effectiveness of various occupations, emphasizing that the appearance of competence can often overshadow actual productivity.
