“We have two ears and one mouth so that we can listen twice as much as we speak.” Epictetus quotes (Greek philosopher associated with the Stoics, AD 55-c.135)

In human natural life, we are listening most of the time more than we speak, while this is called discriminative and passive listening which you are listening to voices with different level of sound and including the body language, but we need to control how to listen and when to concentrate on listening by managing and understanding listening skill especially on a career like analyst.
