"Are you what is called a happy man? Well! you are sad every ..." — Victor Hugo quote meaning

Are you what is called a happy man? Well! you are sad every day. Each day has its own great grief or its little care. Yesterday you were trembling for a health that is dear to you, to-day you fear for your own; to-morrow it will be anxiety about money, the day after to-morrow the diatribe of a slanderer, the day after that, the misfortune of some friend; then the prevailing weather, then something that has been broken or lost, then a pleasure with which your conscience and your vertebral column reproach you; again, the course of public affairs. This without reckoning in the pains of the heart. And so it goes on. One cloud is dispelled, another forms. There is hardly one day out of a hundred which is wholly joyous and sunny. And you belong to that small class who are happy! As for the rest of mankind, stagnating night rests upon them.
