If you begin by sacrificing yourself to those you love, you will end by hating those very people. This follows as surely as night follows day. A house built on sand, no matter how devotedly, is doomed to be washed away with the rain. All things are temporary: belief in them is sure to end in disappointment.
The old-aged are often bitter about life. They feel cheated that all they had been given has now been taken away. Gone is the strength and beauty of youth, gone are the children, friends are dead, dreams of the future are no longer possible, and past achievements seem empty. There is nothing to savour from the past, nor anything in the future or the present. Time will strip all things bare - do not doubt it for a moment!
We must learn that this life is not ours to lose. Not even temporary rights are ours.
