The combination of understanding my own personality and my core fears assisted me to understand myself and deepen my relationships with other people. Maybe you are a Financial Adviser that is giving advice to clients but still do not understand certain aspects of yourself or your clients.
As part of my coaching I use the Enneagram model, which refers to nine different interlocking personality types – each one representing a model which explains how different people think, feel and act in relation to the world, others and themselves.
