As a man we have to realize necessity of other . We would no take only facility, we also fill up their need in different way or according to his wish . We must believe that every man has want, need and demand. We also believe that human want is unlimited. But we are not capable to fill up all type of demand . We have more and more limitation . In contrast , we should not be greedy and should not take negative attitude. We have to be proactive and optimistic in every step in our life.
Moreover, we are all dependent on each other because of the past of nature. In addition, because none of us are willing to meet all are own needs. That is why we, the society, the state and even the world, have to ensure that we have a good relationship with each other. So the main thing is that everyone is good, I am good too. Besides, since we are dependent on each other, we should always look not only at our own interest , but also at the advantages and disadvantages of others. Otherwise, the mental element of being good as a human being in the society will not be friendship, love and harmony. Because only with one’s own good, with this selfish mentality, real peace of mind, happiness can not be achieved.
