给一个人火，他能温暖一天；但把他点燃，他能温暖余生。
Give a man a fire and he's warm for a day, but set fire to him and he's warm for the rest of his life.
译文：奢侈无度可以让家业衰败，过于吝啬也可以让家业衰败；过于愚笨可以坏事，精明过于也可以坏事。赏析：挥霍无度，浪费钱财，过分追求物质享受，再多的家产也可以被败光，而过分吝啬，不懂得散财，不懂得让金钱为我所用，再多的家产都无法产生价值。只会赚钱，不会用钱，金钱将失去意义；只会用钱，不会赚钱，金钱无处可来。人如果愚钝不开，就不会明白世间的道理，做事毫无章法，自然难以成事；而人过于精明，不懂得收敛锋芒，处处要占上风，处处算计别人，做事也难以成功。
The work is about presence and absence.
