One day, an expert in time management was speaking to a group of students and, to drive home a point, 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. He then asked the group once more, "Is this jar full?"

By this time the class was on to him. "Probably not," one of them answered. "Good!" he replied. He reached under the table and brought out a bucket of sand. He started dumping the sand in the jar and it went into all of the spaces left between the rocks and the gravel. Once more he asked the question, "Is this jar full?"

No!" the class shouted. Once again he said, "Good." Then he grabbed a pitcher of water and began to pour it in until the jar was filled to the brim. Then he looked at the class and asked, "What is the point of this illustration?" One eager student raised his hand and said, "The point is, no matter how full your schedule is, if you try really hard you can always fit some more things in it!"
“没满！”学生们大声说。他再一次说：“很好！”然后他拿过一壶水倒进玻璃瓶直到水面与瓶口平。抬头看着学生，问道：“这个例子说明什么？”一个心急的学生举手发言：“无论你的时间多少，如果你确实努力，你可以做更多的事情！”

"No," the speaker replied, "that's not the point. The truth this illustration teaches us is if you don't put the big rocks in first, you'll never get them in at all. What are the 'big rocks' in your life? Time with your loved ones, your education, your dreams, a worthy cause, teaching or mentoring others? Remember to put these big rocks in first or you'll never get them in at all."
“不！”时间管理专家说，“那不是它真正的意思，这个例子告诉我们：如果你不是先放大石块，那你就再也不能把它放进瓶子了。那么，什么是你生命中的大石头呢？也许是你的道德感、你的梦想？还有你的---切切记得先去处理这些大石块，否则，一辈子你都不能做！”
