The world needs its human population to be vitally alive. For that to be true of us, we have to be interested in what we are doing, and understand it to be necessary work, vital work, important in a substantive way to the welfare of ourselves and our neighbors. We have to be doing work that interests us and is useful and helpful. Show of hands? My present thesis is that the quality of our moods, the number and seriousness of our symptoms, the state of our health, and the length of our life are reflected in the degree to which our work is interesting and useful. Check me out on that. Make inquiries. Conduct research studies. Let me know what the evidence shows. But only if you are interested in doing it and think the results will be useful.
