The Glass Jar: Rocks, Pebbles, Sand and Water

The “rocks in a glass jar demonstration” is a familiar time management technique that is used to illustrate the importance of establishing priorities. A glass jar is filled with large rocks then pebbles. This is followed by sand and water. The purpose of the exercise is to teach participants that they need to put the large rocks in first or they will not fit later. The large rocks symbolize the priorities in our lives that are aligned with our values and goals.
