Another fragment.

Life is like that. Even the bad experiences of life provide their special contribution. But a word of caution here for those who neglect the need for care and attention to life’s disciplines. Everything has its price. Everything affects everything else. Neglect your own discipline and there will be a price that must be paid. All things of value will be taken for granted with the passing of but a little time. That’s what we call the law of familiarity. Without the discipline for paying constant daily attention, all things become vulnerable.

Can someone explain what he's talking about?
