"It is not healthy to be thinking all the time. Thinking is intended for acquiring knowledge or applying it. It is not essential living."

Your children should have it impressed upon them that their adult life-style will bear very little resemblance to yours and that they should now be acquiring knowledge, skills, values, and tastes that will sustain them in less materially affluent circumstances. On the other hand, the fresh insights and imaginations of your children may help you find a viable future while there's still time.
