Many of us like to express ourselves, other than listening other. We are trying to let others understand what we are thinking. We talk too much. But I find it is better to listen others than expressing ourselves.
Many people are proud of saying that they are good psychological experts, but in my opinion, most of them are not, because they don't know the importance of listening others. The truth is, in most case, your clients just want to express themselves to you, other than listen to your advice.
So keep one thing in mind, learn to listen to others.
