Years ago, an old scholar recommended me a book by economist E. F. Schumacher called, Small is Beautiful: Economics as If People Mattered, from which he particularly mentioned the following quote:
"Everywhere people ask: 'What can I actually do?' The answer is as simple as it is disconcerting: we can, each of us, work to put our own inner house in order. The guidance we need for this work cannot be found in science or technology, the value of which utterly depends on the ends they serve; but it can still be found in the traditional wisdom of mankind. "
