The world has been struggling for many years to differentiate between healthy and unhealthy behaviours. Religions, cultures, values and ignorance have even been introduced to try to separate the divide between healthy and unhealthy.
Ultimately, nature provides the answer. Healthy grows you, nurtures your soul, feeds your desires and satisfies your need to feel confident about your destiny. Unhealthy shrinks you, feeds your ego and satisfies your short term fears.
It may be wise in the future to look at human development from this perspective because much of what is done in the name of good corporate development, and the behaviours that result, are based on unconscious models of human development.
