When we do not have enough interest in the world around us, then we are thrown back into ourselves. Taken all in all, we have to say that if we look at the chief damages created by modern civilization, they arise primarily because people are far too concerned with themselves and do not usually spend the larger part of their leisure time in concern for the world but busy themselves with how they feel and what gives them pain … And the least favorable time of life to be self-occupied in this way is during the ages between 14, 15 and 21 years old.
The capacity for forming judgments is blossoming at this time and should be directed toward world-interrelationships in every field. The world must become so all-engrossing to young people that they simply do not turn their attention away from it long enough to be constantly occupied with themselves. For, as everyone knows, as far as subjective feelings are concerned, pain only becomes greater the more we think about it. It is not the objective damage but the pain of it that increases as we think more about it. In certain respects, the very best remedy for the overcoming of pain is to bring yourself, if you can, not to think about it.
