A philosophy professor stood before his 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 proceeded to fill it with rocks,
about 2 inches in diameter. He then asked the students if the jar
was full?

They agreed that it was.

So the professor then picked up a box of pebbles and poured them
into the jar. He shook the jar lightly. The pebbles, of course,
rolled into the open areas between the rocks. He then asked the
students again if the jar was full.

They agreed it was.

The professor picked up a box of sand and poured it into the jar.
Of course, the sand filled up everything else. He then asked once
more if the jar was full.

The students responded with a unanimous - yes.

The professor then produced two cans of beer from under the
table and proceeded to pour their entire contents into the jar
- effectively filling the empty space between the sand. The
students laughed.

"Now," said the professor, as the laughter subsided, "I want you
to recognize that this jar represents your life. The rocks are the
important things - your family, your partner, your health, your
children - things that if everything else was lost and only they
remained, your life would still be full. The pebbles are the other
things that matter like your job, your house, your car. The sand is
everything else. The small stuff.

"If you put the sand into the jar first," he continued, there is no
room for the pebbles or the rocks. The same goes for your life. If
you spend all your time and energy on the small stuff, you will
never have room for the things that are important to you. Pay
attention to the things that are critical to your happiness. Play
with your children. Take time to get medical checkups. Take your
partner out dancing. There will always be time to go to work, clean
the house, give a dinner party and fix the disposal. "Take care of
the rocks first, the things that really matter. Set your priorities.
The rest is just sand."

One of the students raised her hand and inquired what the beer
represented.

The professor smiled. "I'm glad you asked. It just goes to show you
that no matter how full your life may seem, there's always room for
a couple of beers."
