“I don't think people listen to my stuff. They just listen to the bullshit.”

Simplified Meaning:

When someone says that people don't listen to their stuff and just listen to the bullshit, they mean that others ignore the important things they have to say and pay more attention to unimportant or false information. Think of a teacher in a classroom giving a lecture full of useful and interesting facts, but students don't focus on that. Instead, they talk about silly rumors or gossip they heard during lunch. Just like that, the person feels that their valuable thoughts and ideas are overlooked while trivial or misleading things get all the attention. This can be frustrating because it feels like their efforts are wasted. If you want to apply this idea in real life, make an effort to focus on meaningful conversations and avoid getting distracted by gossip or nonsense. Listen carefully to people who are sharing valuable information, and try not to get caught up in trivial matters. By doing so, you show respect to others and can learn more useful and important things.
