[Vocabulary] To be not interested/Not to interest

[Mr.Lucky_One]

Someone tells me something that I don't want to listen to, because I don't find it interesting or useful for me.
How to express this better, "I am not interested" or "It doesn't interest me"?

"I am not interested"

No, 'I am not interested' is normal and natural.
