A philosophy professor stood before his class and had some items in front of him.

When the lecture began, wordlessly he picked up a large, empty, mayonnaise jar and proceeded to fill it with rocks about 2" in diameter.
He then asked his 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 rocks.
He then asked his students again if the jar was full ?
They laughed and agreed that it was.

The professor then picked up a box of sand and poured it into the jar.
Of course, the sand filled up the remaining spaces.

"Now" said the professor, "I want you to recognise that this is your life.
The rocks are the important things -
your family, your partner, your children, your health -
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 -
your job, your house, your car.

The sand is everything else - the small stuff.

If you put the sand into the jar first, 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 check ups, 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".

But then  .......
A student then took the jar - which the other students and the professor agreed was full -
and proceeded to pour in a glass of beer.
Of course the beer filled the remaining spaces within the jar making the jar truly full.

The moral of this tale is:
No matter how full your life is, there is always room for a BEER !
