-Sharing 2-
Sharing is so important and we need to teach kids when they were young. Classic example of sharing that comes to mind is two kids with a single toy. Sharing will see both kids getting a chance to play with the toy but neither of them will have sole control. Essentially, the kids must learn to compromise since only one toy is available for both of them.
The kids learn that they must make sacrifices in the process which is roughly how the world works. We cannot get all the good stuff and compromises have to be made. Two parties might have to work together to both benefit from the cooperation. We might get less than we wanted but we get something rather than failing by ourselves and gain nothing at all.
We have all seen selfish and self-centered people in our lives. They want everything to themselves thinking that the world owes them. How willing are you to become these people's friend? Quite unlikely since such a one-sided situation is nothing people want to be in. At the very least, people want friends who will have their back when required. You won't get any of that from a selfish person.
If a person, from a young age, was spoiled by parents, then he/she will expect to get anything he/she desires. The real world, sadly, doesn't work that way. The issues lies in that, as a person get older, it much harder to learn how to share. Changing these sorts of mentality isn't easy for adults and, the longer a person delays, the worse it gets for the person's life. After all, life does have to teach some of us the hard way if we don't learn early on.
Something else gained from sharing is learning how to cope with disappointment. If people learn to compromise, they learn that they cannot have everything to themselves. Sacrifices had to be made so both sides can benefit. This can lead to some disappointment since a person might want the whole thing. If kids were taught at a young age that disappointments will happen and can respond maturely, they will get through life much easier.
