     A group of graduates, successful in their careers, got together to visit their old university professor.

Conversation soon turned into complaints about stress in work and life.  

     Before offering his guests coffee, the professor went to the kitchen and returned with a large pot of

coffee and a variety of cups-porcelain, plastic, glass, crystal, some plain looking and cheap, some

exquisite and expensive-telling them to help themselves to the coffee.

     When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice

looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is normal for

you to want only the best for yourselves, that is the source of your problems and stress. Be assured that

the cup itself adds no quality to the coffee. In most cases it is just more expensive and in some cases

even hides what we drink. What all of you really wanted was coffee, not the cup, but you consciously

went for the best cups.  And then you began eyeing each other's cups.

     Now consider this: Life is the coffee; the jobs, money and position in society are the cups. They are

just tools to hold and contain Life, and the type of cup we have does not define, nor change the quality

of life we live. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has

provided us. "

     God brews the coffee, not the cups. Enjoy your coffee!

     "The happiest people don't have the best of everything. They just make the best of everything. "

     Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God.
