A story about jars, stones, sand, and pebbles. The story brings up the point about the importance of prioritizing how we spend our time.
The jars represent all the time we have in our lives. The rocks are equivalent to the most important projects and things you have going on, and the sand and pebbles are representing the things you could live without or small things that don't mean much in your life. In order to have a more effective and efficient life, pay attention to the “rocks,” because they are critical to your long-term well-being. The metaphor here is there are countless stones in the world that you wanna obtain, but the space of the jar is limited. It is impossible to have all the stones you want so you need to make choices.
