A philosophy professor stood before his class. He picked up a large empty mayonnaise jar and proceeded to fill it with rocks. He then asked the students if the jar was full? They agreed that it was. The professor picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else. "Now," said the professor, "I want you to recognize that this is 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 sand is everything else. The small stuff.
"If you put the sand into the jar first, there is no room for 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."
But then a student took the jar which the other students and the professor agreed was full, and proceeded to pour in a can of beer. Of course the beer filled the remaining spaces within the jar making the jar truly full.
The moral of this tale is: That no matter how full your life is, there is always room for BEER.
And there you have it.
