Work is a rubber ball. If you drop it, it will bounce back. The other four balls – family, health, friends, integrity – are made of glass. If you drop one of these, it will be irrevocably scuffed, nicked, perhaps even shattered.
Your work life is divided into two distinct areas – what matters most and everything else. You will have to take what matters to the extremes and be okay with what happens to the rest. Professional success requires it.
