Philosophy of life

I always love this philosophy, even I've read it several times. I'll share it with you.
A professor take a big tin, then filled it full with golf balls, asked the students whether it is full, and they agreed.
Later, he pour in the stones, shake it, and all the stones fill the empty space in the tin, then the professor asked the student, is the tin full already? They agreed.
Then, the professor fill in the sand to the tin, and of course the sand fell down to the empty space between golf balls and the stones. He asked the students again, and they said it is full already.
The professor pour in 2 cups of coffee, and the coffee was effectively absorbed into the sand, the students smile.
Now, I want to let you learn about life. This tin is your life.
The golf balls are the important things in our life: God, family, children and health
Even if, all of the others gone, and only the golf balls left, your life is still full.
Stones are your job, house, car.
Sands is all the small stuffs.

If you fill up the tin with the sands, then there would be no room for the golf balls and the stones. The same things if you applied in your life.
That's why we need to spend time for the important things, spend your time with your family, the one that you love, your children. Spend your time to do some health check up.
Take your partner for dinner and family gathering.
Pay attention to the golf balls, make it as first priority. Then, the stones and sand.

One of the students asked, then what is the coffee?
The professor said, I'm glad that you asked. It means that how full is your life, there is space to have a cup of coffee with best friend.

Hope that this stories will enlighten the way you think, and so do I trying to keep all the golf balls before the others.
