Why do people like "Keyboard Man" appear on the Internet?

Keyboard man generally refers to those who are timid and have nothing to do in life but act as good teachers on the internet. This is an escapist and self-abased network. Some of them may be down and out on the Internet in real life, but they have become rich owners. Some of them are useless in real life, but they have become big cows in the eyes of others in the network. Because, separated by a network, they don't care about other people's eyes, because no one really knows themselves at all. The network has become a platform for them to write their own' great life', and they can find a sense of existence and superiority on the network.

This is actually a self-deception, irresponsible for themselves. You should know that the life you want, the person you want to be, needs to come out step by step in real life, not all kinds of boasting on the Internet.
