Final answer:
The requested quote by Steve McQueen is not found in "The Rich Boy" by F. Scott Fitzgerald or in the other literature excerpts provided. There seems to be some confusion regarding the source and the quotes are from different contexts and works.
Step-by-step explanation:
The quote by Steve McQueen that is often mentioned is not actually present in the book "The Rich Boy" by F. Scott Fitzgerald or any notable literature. The quotes provided suggest a mix-up with quotes attributed to different characters and other works. For instance, quotes from Zane Grey's novel involving characters like Venters and racehorses refer to a different context altogether. Similarly, the quotes from LibreTexts are more reflective of aphorisms that can be found in classical philosophical texts and do not align with McQueen's typical attributions. The quotation from an expert referencing a classical philosopher such as Aristotle and associated with Johnson's idea indicates the use of authoritative voices to strengthen an argument, but does not relate to Steve McQueen.
