The conviction that you, or anyone else, knows what you already need to know could be one of biggest challenges you and/or other people face.
Calming our emotions and looking deeply, we can become aware of our feelings and of whatever misperceptions we might have that could prevent us from hearing and understanding the other person.
One of the deepest things we can learn is we should not be too sure of our own ideas. Don’t be fooled by your perceptions. Even if you are sure you are seeing clearly, check again. Keep an open mind. Be ready to let go of your views.
