One day, an expert in time management was speaking to a group of students and, to drive a point home, used an illustration those students will never forget. As he stood in front of the group of overachievers he said, "OK, time for a quiz." He pulled out a one-gallon, wide-mouth jar and set it on the table in front of him. He also produced about a dozen fist-sized rocks and carefully placed them, one at a time, into the jar. When the jar was filled to the top and no more rocks would fit inside, he asked, "Is this jar full?" Everyone in the class yelled, "Yes." The time management expert replied, "Really?" He reached under the table and pulled out a bucket of gravel. He dumped some gravel in and shook the jar, causing pieces of gravel to work themselves down into the spaces between the big rocks.
