| A professor wanted to teach his class a lesson on life, so he stood one day at the front of the room, with a large mouthed mason jar. He proceeded to fill the jar with fist sized rocks. Then he looked at the class and asked, "Is it full?" "Yeah," an unsuspecting student answered. "Really?", the professor asked, and proceeded to pour a bag full of pebbles into the spaces between the rocks. "Now is it full?" "Probably not", replied another student starting to catch on. "Good," he answered, and began to pour sand into the crevices that were left. "But it's still not filled," he continued, and then poured water into the jar until it reached the very top. "Now it's full. Can anyone tell me what the point of this demonstration is?", he propostioned. One student sheepishly answered, "No matter how full our schedules are, we can always fit more in." "No," the professor answered, "the point is that if you didn't put the big ones in first, you never would have got them in at all." |
