If you want to speak your mind and want the others to know the beauty of it without allowing them to respond, just write a blog or deliver a speech.
You can start with why, where, when, what, who, and how (5 W’s and 1 H).
You need to go with the flow. You should let go of these thoughts and not disrupt the ongoing conversation.
If you don’t have any knowledge about the topic, admit it openly that you don’t know. Why lie about it?
