"The Time Keeper" by Mitch Albom explores the concept of time and its significance in human life. The story follows Dor, the first man to measure time, who learns that time is a precious resource not to be squandered or hoarded. Through his journey, he realizes that while time can be counted, it should be cherished and experienced fully rather than obsessively tracked. This profound realization stems from the idea that time cannot be given back once it's lost, underscoring the importance of embracing each moment.

The narrative delves into the consequences of humanity's relationship with time, as Dor witnesses how people's attachments to it can lead to regret and dissatisfaction. The quote "Time is not something you give back" encapsulates the essence of the book, highlighting that every second is irreplaceable. Albom's writing encourages readers to reflect on how they spend their time and to prioritize meaningful experiences over the relentless pursuit of time management, ultimately advocating for a life lived with intention and appreciation.
