Throughout our lifetimes on this beautiful planet we have developed ways of viewing and reacting to the world that determine our path in life, how hard we work, our relationships and our daily reactions and emotions.
This might sound strange, but finance is, to a great extent, psychology. The way we view the world around us, our decisions and the resulting behaviors whether we buy or sell, are happy with our interest rates or not, feel taken care of by our bank are all driven by the psychology of perception.
