Take educating children as an example, we should do things in a planned and step-by-step way.
Once, a teacher was giving a class to a student. He took out a pile of fist-sized stones and carefully put them into the glass bottle. It was not until the stone was higher than the bottle mouth and could no longer be put down that he asked, "Students, do you think the bottle is full?"
Almost all the students answered in unison: "full." The teacher asked, "Really?" He reached out and took out a bucket of stones from under the table, poured some into it, knocked on the glass bottle wall and filled the gap between the stones below.
Is the bottle full now? "The teacher asked again. This time, the students understood, "No!" A student boldly replied.
Very good! "said the teacher. He held out his hand, took out a bucket of sand from under the table and began to pour it into the glass bottle slowly. Sand fills all the gaps between stones and gravel. He asked the students again, "Is the bottle full? "
"Not full!" The students said in unison. He expressed his satisfaction again and said, "Good."
Then he took a pot of water and poured it into a glass bottle until the water was flush with the bottle mouth. He looked up at the students and asked, "What does this example show?"
An impatient student raised his hand and said, "Teacher, it tells us that no matter how tight your time is, as long as you really work hard, you can still have time to do more."
"You are only partly right," said the teacher. This example also tells us that the size of a bottle is limited. If you don't enlarge the stone first, you can never put it in the bottle again. Students, everyone's time is limited, so no matter what you do, remember to deal with those' big stones' first, otherwise, you can't deal with them any more. "
Do things with a plan, have priorities, and plan the order of doing things. There are some important or time-limited things to do first, otherwise, like the "big stone" in the story, it will never be put into the bottle again.
The enlightenment of growth is here.
Later, when teaching students, he also made an interesting experiment. He filled the bottle with big stones, gravel, sand and water.
It is used to warn students that in a limited time, they should make plans, arrange steps, prioritize everything and do everything in an orderly way.
