Meaningless becomes meaningful if enough people believe in it.
So if a person knows a lot of people in a group, then it is easy for him to be perceived meaningful. If a person doesn’t know a lot of people in a group, it is that much more difficult to be more meaningful.
This is also one of the important reasons why networking is important. Networking will help you build meaning and gain support towards your side of the argument. People always do this in all sides of life.
