Life story

Professor of Philosophy, before the lecture comes into the room and lay on the table a few different things. When classes begin, he silently takes a large, empty, a jar of mayonnaise and fills it with large stones. Then ask:
 - The jar was full?
 - Yes! - Agree to the students.
The professor then picked up a box with small pebbles and poured it into the same bank. He chatted a little jar and pebbles, of course, filled the open areas between the rocks. He again asked the students:
 - Bank is full?
They laughed and agreed that the bank is full. Then the professor picked up a box of sand and poured it
in a jar. Of course, the sand fills the rest of the space.
 - Now - said the professor - I want you to understand that this is - your life. Stones - important things - your family, your friends, your health, your children. If everything else was lost and only they remained, your life would still be full. Pebbles - other things that matter like your job, your house, your car. Sand - everything else, it's just little things in life. When you first nasyplete sand into the jar, there is no room for the pebbles and stones. The same goes for 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. Take care of the rocks first, it really matters. Set your priorities. The rest - just sand. But, there's one student, went to the bank, which, according to others, was complete, and there poured out a glass of beer. Of course, the beer filled the remaining space in the bank, which has become completely full.

Moral of the story: no matter how full your life, there is always a place for a beer!
