Pls answer will give you 20 points read this excerpt from "what i hope to leave behind.” one of the things which i hope are coming home to us with a lessening of the abstract desire for money is an appreciation of the fact that some people have an ability to enjoy where others have not, and that one of the things that we must do is to give that ability to enjoy to more and more people. choose the best paraphrase of this sentence. money and material wealth are abstractions that never make people happy, but if we learn to find joys in the simple things in life, such as family, community, and nature, we can learn to appreciate a life that does not require money. one of the things that i hope are coming home to us with a lessening of the abstract desire for money is an appreciation that we are all connected and that we can all work together to make the world a joyful place. as soon as we place little importance on money, we will gain an appreciation of the fact that some people have an ability to enjoy life and that one of the things that we must do is to give that ability to enjoy to more and more people. i hope that as material wealth becomes less important, we will begin to appreciate people who have the ability to enjoy life, and the more we teach this ability, the more people will enjoy life.
