Time is a sword: this is an aphorism, meaning if you don't cut it, it will cut you. This term can also be interpreted as time must be used as well as possible, for example, use the best possible time before it is time to get sick, study in youth before old age comes.
Family is happiness.
Oh I see. But a sword is useless without someone to wield it. sincerely speaking I still don't understand the aphorism. But it's all good.
The point of it all is to use time well so as not to be negligent.
