A professor stood in front of his class and placed a large glass jar on the table.

Without saying a word, he filled the jar with golf balls. He asked the class if the jar was full.

They all said yes.

He then picked up a bag of small pebbles and poured them into the jar. The pebbles settled into the spaces between the golf balls. He asked again if the jar was full.

They agreed it was.

He then poured in a bag of sand. The sand filled every remaining gap. He smiled and asked once more if the jar was full.

Everyone said yes.

Then he picked up two cans of coffee and poured them both in. The coffee filled the remaining space perfectly. The class laughed.

He looked at them and said:

"This jar is your life."

"The golf balls are the things that truly matter. Your health. Your family. Your closest friends. Your purpose. If everything else was lost and only these remained, your life would still be full."

"The pebbles are the other things that matter. Your job, your home, your hobbies."

"The sand is everything else. The noise. The small stuff. The things that feel urgent but are not important."

He paused.

"If you put the sand in first, there is no room for the golf balls."

A student raised her hand. "What about the coffee?"

He smiled. "No matter how full your life gets, there is always room for a cup of coffee with a friend."

What this story teaches.

It is easy to fill your days with the sand. Notifications. Small tasks. Obligations that feel important but are not.

The golf balls get squeezed out. And then one day you realize you have been very busy but not very full.

The work is knowing which things are golf balls. And then being stubborn enough to put them in first, before the day fills up around them.

Your health is a golf ball. Your people are golf balls. Your peace of mind is a golf ball.

Not everything deserves space in the jar. Choose carefully what you let in first.
