When things in your life seem almost too much to handle, when 24 hours in a day are not enough, remember this story about a jar and a cup of coffee.
A professor at a Christian college stood before his philosophy class with several items in front of him.
When the class began, he picked up a very large and empty mayonnaise jar and proceeded to fill 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 them into the jar. He shook the jar lightly and the pebbles rolled into the open areas between the golf balls. He then asked the students again if the jar was full. They nodded their approval.
The professor next picked up a box of sand and poured it into the jar. Of course, the sand filled in the gaps. He asked once more if the jar was full and the students responded with a unanimous "yes."
