I'll answer based on the information I have thus far.
I don't know for sure what the problem is.
However I will take a guess. People who are not interested in what others have to say generally are either self-centered or look down on others. The solution for both is empathy.
I define empathy as seeing other people similar to yourself.
If you're self-centered, you are focused on your thoughts and wants. For example you want to be entertained. You aren't focused on the thoughts of others, or how you can help them. Ultimately this is because you view yourself as different than others. Which is why you treat your thoughts differently. If you were the same, wouldn't you treat them with the same love you think you deserve?
If you look down on others, you might listen to what they have to say, but you dismiss it or don't care. The reason here is because you view yourself as different - a superior.
The solution is to view yourself more similar.
Imagine if you viewed yourself as similar to others. Then you'd view yourself as average. Subsequently 50% of the population is better than you at something. You'd have so much to learn from so many people - of course you'd want to listen to their insightful opinions!
Also, if you viewed others as similar, then you'd want to care about them. I don't know how difficult your life has been, but let's assume it's been pretty difficult. Imagine if everyone you came across had at least the same amount of difficulty in their life. Wouldn't you want to help them, as you wish, perhaps, people had helped you?
How do you do this? Well I'd say start with this assumption: "if I had the same experiences as someone else, I'd think the same as them." Maybe you disagree with that right now. But try learning some perspectives and disprove it. Meaning learn about people, what they did and why - ask yourself "would I really do something different in the same situation" I've done this exercise and came to the conclusion I would literally do the same things as other people given the same situation. Over and over I find myself thinking "wow, if I was in a constantly negative environment and never knew what love was like, I'd probably think everyone was bad and be a worse person". It's scary. To think that inside me literally lies to potential to be an evil dictator. Of course the same potential lies to be a spiritual guru. The end result is it's hard to judge others because in the process I'd be judging myself.
Ironically you perhaps lack empathy because you don't talk to people. Which is why you don't want to talk to them.
