"For most people, money is never just money, a tool to accomplish some of life's goals. It is love, power, happiness, security, control, dependency, independence, freedom and more. Money is so loaded a symbol that to unload it--and I believe it must be unloaded to live in a fully rational and balanced relationship to money--reaches deep into the human psyche. Usually, when the button of money is pressed, deeper issues emerge that have long been neglected."
