The past is a shadow that follows us, but it is up to us to decide whether it will darken our future.

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。

我想激励人们。我希望有人看着我说，‘因为你，我没有放弃。’
