I don't mean just seeing something nice and wanting to have something like that. Some people would not mind doing anything to take what belongs to another. Why do we have people like that?
I think people desire what's not their because of being envy and jealousy. It is not right to aim for what's not ours and we must work hard for it instead. Competition is also a common reason why people urge to have more than what they have. People compete and don't want to be left behind. We must not have this kind of attitude but must work hard for what we want.
