You’re making things a part of your life by simply thinking of them. Whether if it is a person, a thing or a feeling, it doesn’t matter. Or if it’s something you hate, like, or love. Generally speaking they’re all the same. When you say you hate something, a thought for example, and you keep drilling it in your head, well tada! You end up hating it more. Because you’re putting some kind of an effort to somehow let it stay in your mind. This is why I don’t believe when someone keeps saying they don’t care about something or someone because they keep talking about it. Because if you didn’t care, why bother mention it? See the point?
