Mr. Holcombe reflects on how some children only realize their own intelligence and potential after their schooling years are over. This delayed awareness means they often miss opportunities to develop and utilize their abilities during their formative years. As a result, they may feel unfulfilled or regretful later in life for not recognizing their talents sooner.

He suggests that this realization can lead to a lifetime of regret, as these individuals become aware of their missed chances and the potential they could have harnessed early on. The quote emphasizes the importance of self-awareness and recognizing one's abilities early to avoid feelings of remorse in later years.
