For me, what I've learned from Steven Covey is very practical. There are four areas: Physical, Mental, Emotional and Spiritual. Money, I think is in the 'physical' classification and health is more important than money also in the physical aspect. If we use money wisely, as a tool, we can improve on all four areas more easily. Some people who obsessed too much and loved money (which should be just a small fraction of the physical area of life) ended up killing themselves.
