When things in your life seem almost too much to handle, when 24 hours in a day is not enough, remember the mayonnaise jar and two cups of coffee.
A professor stood before his philosophy class and had some items in front of him.
When the class began, wordlessly, he picked up a very large and empty mayonnaise jar and filled it with golf balls.
He then asked the students if the jar was full. They agreed that it was.
The professor then picked up a box of pebbles and poured it into the jar. He shook the jar lightly. The pebbles rolled into the open areas between the golf balls.
He then asked the students again if the jar was full. They agreed it was.
