In today's competitive society, everyone is bound to suffer from stress. These psychological and social stressors include the breakup of intimate romantic relationships, death of a family member or friend, economic hardship, role conflict, work overload, unemployment, discrimination, poor physical health, care-taking for elderly parents, accidental injuries, and intentional assaults on physical safety. Chronic strain can cause physical, emotional and behavior- al disorders which can in turn affect your health, vitality, peace-of-mind, as well as personal relationships and eventually erode quality of life. The most important thing is to learn to relieve stress. Otherwise, it will lose physiological balance and lead to serious psychological problems, such as depression, mental disorder and so on. Some unlucky people who can't deal with their stress, may resort to suicide or other means of hurting themselves. But none of these is advisable. Keeping a healthy and positive state of mind and facing reality bravely are the preferable ways to overcome stress.

Human life needs a peace of mind. While others are wining and dining, I am content with plain tea. Not dazzled by others' aura of success and glory and being aware where the applause goes, 1 am still satisfied with my simple pleasure. Because I am conscious even if we join in the rush, there is no hope waiting for us. What a blind follower to do is to tail after the winners. The only alternative is to create one's own wonders. Enjoying the placidity of mind means not hiding oneself in a heaven, but keeping a peaceful state of mind in chaos, just like the lotus growing in the mud without being tainted. Only those who have attained such a degree can be masters of their own destiny, contenting themselves with the simplest pleasure.

        My View on Ecotourism
   As we all know, the booming tourist industry has played a positive role in meeting the cuhur- al needs of the public, introducing the country to foreigners, showcasing the brilliant history and culture to the outside world, which in turn has spurred the development of transportation, building and telecommunications industries, plus the development of the catering, recreational and souvenir trade, and has given birth to many new industrial sectors, which provide more job openings and generate income and tax revenues. However, the negative effect of tourism on our society, especially on our environment can't be ignored. For example, tourism may cause serious environmental pollution and destroy many beautiful scenic spots. It may also break the ecological balance and lead to the extinction of some species because too much tourism may destroy the natural habitats of wildlife and too much tourists flooding the tourist attractions pose potential risks to the preservation of cultural relics.
   Given the circumstances above, tourism pundits warn that we must attach great importance to the near-term and long-term harm to the environment done by the development of tourism. They advocate ecotourism, i.e. sustainable tourism--responsible travel to natural areas, that conserves the environment and improves the well-being of local people and speculate that there will be an ecotourism boom around the world whose theme is to go to nature reserve and go back to nature.
   In order to encourage preservation, conservation and sustainability of natural and cultural re- sources and minimize the negative impact on the environment, our government has made some guidelines for eeotourism and taken some measures to achieve its goals. First, the government should provide direct financial support and benefits for conservation.  Second, the government should make effort to conserve biological and cultural diversity by strengthening protected area management systems and increasing the value of sound ecosystems.  Finally, the government
should promote the sustainable use of biodiversity by generating income, jobs and business opportunities in eeotourism and related business networks.
   As a citizen, everyone should take a part and contribute actively to the conservation of natural and cultural heritage.  We should build environmental and cultural awareness and respect. Tourism planners and tourists alike are learning to beware of mass and unplanned tourism and strive for sustainable tourism development, because well-planned and managed ecotourism has proved to be one of the most effective tools for long-term conservation, sustainability and diversity. Only in this way can we achieve the sustainable development of ecotourism while carrying for- ward our national culture.
