What is Happiness?
1. The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true, more often than not things that lead to happiness involve some pain.
2. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement.
3. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment （应承担的义务）. For commitment is in fact quite painful. The single life is filled with fun, adventure, and excitement. Marriage has such moments, but they are not its most distinguishing features.
4. Couples with infant children are lucky to get a whole nights sleep or three-day vacation. I dont know parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
5. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

Water
Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts （干旱） are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the worlds population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
But that doesnt have to be the outcome. Water shortages do not have to trouble the world－if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation （灌溉） water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions （凹地） and pumping it to nearby cropland.
No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.
