The twist placed on this well known story illustrates importance of Attitude priorities:

A professor of philosophy stood before his class with some items in front of him. When the class began, wordlessly he picked up a large empty mayonnaise jar and proceeded to fill it with rocks about two inches in diameter. He then asked the students if the jar was full.

They agreed that it was full.

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

They chuckled and agreed that it was indeed full this time.

The professor picked up a box of sand and poured it into the jar. The sand filled the remaining open areas of the jar.

Of course the rocks represent truly important things, such as family, health and relationships. If all else was lost and only the rocks remained, your life would still be meaningful. Our Attitudes toward the rocks, pebbles and sand decide their priority. The pebbles are the other things in your life, such as work or school. The sand signifies the remaining “small stuff” and material possessions.
If our Attitudes toward the sand in our lives gives it priority over what really matters than we won’t have room for the things that really matter.
Our health is one of the things that matters most. Finding time in the day for fitness or participating in other athletic endeavors should be considered a “rock” for us all. Physiologically, working out releases endorphins in the body. These endorphins are natural pain-relievers. The natural high we experience after a workout ensures us we’re physically ready as possible.
This natural high has the potential to positively influence our daily interactions by making us feel better about ourselves. If our Attitudes toward fitness make fitness a rock solid priority, we’ll reap the rewards.
Pay attention to the things in life that are critical to your happiness and well-being. Take time to get medical check-ups, play with your children, go for a run, write your grandmother a letter. There will always be time to go to work, clean the house, or fix the disposal.
Take care of the rocks first – things that really matter. Have your Attitudes emphasize the things that truly matter, so you won’t end up with nothing but a bunch of sand.
