Let me add a couple to this list.
1. No amount of knowledge or discussion will make a person accept something they don’t want to accept.
2. To truly listen means to place yourself mentally and physically in a vulnerable state. Because you will likely hear things that run contrary to your experience, beliefs, and worldview. Judging people is often a self protection mechanism; which means you will almost never listen to someone.
3. Listening often means not jumping to a solution; but absorbing and processing someone’s pain. Product managers for example are quick to jump to a solution, a new feature, or they’ll push the request off as “oh, ok, we’ll make a ticket for that ”
When in actuality, they should be listening to the use case, looking for the pain, and finding a way to solve the pain points. As opposed to trying to understand what feature the user wants to request.
