The quote from Larry McMurtry's "Streets of Laredo" reflects on the commonality of mediocrity in human achievement. The speaker observes that, throughout his life, he has seen that few men have been able to accomplish significant feats. While many strive for greatness, only a select few manage to attain even one notable success, suggesting that exceptional accomplishments are rare.

This perspective highlights the challenges and limitations that individuals face in their pursuits. It emphasizes the idea that while ambition is widespread, the actual realization of great achievements is often elusive. McMurtry's insight serves as a reminder of the difficulty inherent in making a lasting impact in one's endeavors.
