In Mitch Albom's "The Time Keeper," the quote "Man rarely knows his own power" reflects the inherent potential within every individual. It suggests that people often underestimate their capabilities and the impact they can have on their lives and the lives of others. This theme resonates throughout the story, highlighting the importance of self-awareness and recognizing one's influence over time and choices.

The narrative explores how individuals grapple with the passage of time and the urgency to make the most of it. By understanding their true power, characters learn to appreciate life more fully, forging deeper connections and pursuing genuine fulfillment instead of merely existing in a cycle of regret and haste.
