Note the individual and subjective nature of each case. No two are alike and there is no reason to expect them to be. Each man or woman must find for himself or herself that occupation in which hard work and long hours make him or her happy. Contrariwise, if you are looking for shorter hours and longer vacations and early retirement, you are in the wrong job. Perhaps you need to take up bank robbing. Or geeking in a sideshow. Or even politics.
Robert A. HeinleinThere are hidden contradictions in the minds of people who "love Nature" while deploring the "artificialities" with which "Man has spoiled Nature.'" The obvious contradiction lies in their choice of words, which imply that Man and his artifacts are not part of "Nature" : but beavers and their dams are.
Robert A. HeinleinHe should have known better because, early in his learnings under his brother Mahmoud, he had discovered that long human words (the longer the better) were easy, unmistakable, and rarely changed their meanings, but short words were slippery, unpredictable changing their meanings without any pattern. Or so he seemed to grok. Short human words were never like a short Martian word - such as grok which forever meant exactly the same thing. Short human words were like trying to lift water with a knife. And this had been a very short word.
