Former listening trainer here. I discovered though training a great many people that a key listening problem is that people's attention wanders away and then back, and as a consequence they miss a lot of what has been said but are not aware this has happened. I found this was common even among professional psychotherapists. Also the easiest way to improve your listening skills is reflective listening. That is where you simply say back to the person the key ideas they expressed to you.
