With your clients and also in your personal life of interacting with other people a question to ask yourself
Do You Know What The Key To Understanding A Person Is?
This was reinforced to me when a client complimented me on being a good listener to them.
LISTENING is the key.
You improve your listening by being an active listener being quiet more than talking and HEARING each part of a person's story, like unlocking each tumbler in a door lock.
