Why listening such a big challenge for most people?

Listening such a big challenge for most people. But it's not me who prefer listening than talking. In meeting, the leader like to talk over and not listen a lot. 

When having a communication, people are usually reluctant to listen carefully for many conditions, as follows :

1. It is not important

When they feel that what other talking about is not important, they won't want to listen carefully. And sometimes, we have friends who love talking. Even they talking about everything, unimportant thing. They just keep looking at them for only honoring the speaker. 

2. It is not interesting

When people think that it's interesting, they will keep listening carefully. In other hand, people get bored and stop to listen because they think it is not interesting.

3. Lack of understanding about the topic

People ignore others just because they are not able to catch what the speaker talking about. They don't understand about the topic which is delivered. They don't have way how to respond it. 

4. Eagerly dominate the conversation

People who are good at talking eagerly dominate the conversation. They can't wait to talk even their partner is talking.

5. Having problem

People who have problems at that time usually always think about it. Their mind is full of thinking about that.

6. Dislike the sender

Actually this point is more personal. The receiver doesn't listen to the sender because they don't like the sender.
