I like this article and agree with a lot of it. However, it doesn't cover the problem of stress. Modern living is filled with areas beyond our control. For example, regulations about our cars (it seems that new requirements are being added annually in Europe). Maintaining our lives seems to cost money and unless we are prepared to drop out of society we have to live within these boundaries and therefore find ways to mange the requirements of that community. However hard we try the stress of modern living seems to quietly erode away at the happiness we build.
mirriek,
Stress is unavoidable. Extreme stress can kill you. But we can still be happy, just have to work at it. If you are in a situation that is highly stressful, do an assessment. How can you change the circumstances or situation? If you are unable to make a change, then work within the stress and learn to accept it. Start by not taking anything too serious. I hope this helps solve your curiosity with stress.
