Peace of mind as a concept ranks right up there with happiness in its importance at least anecdotally. I don't know what the research would say, but it is commonly cited by adults as something desirable for themselves and other non related adults especially if they are in sales. Like happiness, peace of mind can be holistic, encompassing all facets of life, or situation specific. One has peace of mind when things are taken care of as in arranging a safety deposit box for valuables. Peace of mind in the broader context is a little more interesting. Does 'everything need to be taken care of?', or is taking care of a limited number of important issues sufficient enough to achieve this state? Does peace of mind mean being at peace with everything regardless of whether they are taken care of or not? What does being at peace mean exactly? More to come... [Russell]
