The balls are work, family, health, friends and integrity.
And you are keeping all of them in the air.
But one day you finally come to understand that work is a rubber ball. If you drop it, it will bounce back.
The other four balls --- family, health, friends, and integrity are made of glass. If you drop one of these it will be irrevocably scuffed, nicked, perhaps even shattered.
And once you truly understand the lesson of the five balls, you will have the beginnings of balance in your life.
