I have kept reading extensively on psychology, philosophy and self improvement for ages. In the recent years, it has accelerated greatly. I still use the same words, but their meaning has drastically changed and is much deeper and interconnected now. And while talking to people about these topics, I realized they interpret the same words very differently compared to me. This is another indicator that words in a language just point to experiences. Only people similar to you can understand you since they would emote to the same things. Even if you get the right feedback, still you can only assume that his/her experience is the same as yours. However, even if not true in an absolute sense, it perfectly satisfies our need for validation and belonging.
