Five balls in the air

Imagine life as a game in which you are juggling five balls in the air.
You may name them: Work, Family, Health, Friends and Spirit. And you are keeping all these in the air. You will soon understand that work is a rubber ball. If you drop it, it will bounce back. But the other four balls--- family, health, friends and spirit are made of glass. Once you drop one of these, it will be irrevocably scuffed( 难以弥补的疤痕),damage or even shattered. They will never be the same.
So, don't run through life so fast that you forget not only where you've been, but also where you are going.
