    Some people believe that if they are wealthy, they will be able to do anything they want, which means happiness. On the other hand, some people believe that holding a high place in the government is happiness, In this way, you have not only money, but also many other things which can't be bought by money. However, other people believe that having lots of money is not happiness, nor is holding a high place in the government. These people value their beliefs, or their wisdom, or their health. They think these can make them happy.

    Here are the ways to help you be happier.

    The secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future, for example, getting into college or getting a good job that we don't enjoy the present. You should enjoy life's simple pleasures, such as reading a good book, listening to your favourite music, or spending time with lose friends. People who have close friends usually enjoy happier and healthier lives.

    The secret of happiness is also to be active. Many people go dancing or play sports. People can forget about their problems and only think about the activities.

    Besides, many people find-happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone. You can help a friend with his or her studies, go shopping to get food for an old neighbour, or simply help around the house.

    Did you know that a new weblog is being created each second? Many of these bloggers are teenagers. While their parents wrote in a diary to express their emotions, or shared their interests by spending time with friends, teens are now using blogs instead. In fact, in the US, one in every five school-aged teens has a blog. Most of these are just chatter, some are funny or clever, but a few have become Internet success.

    For example, Chloe Spencer's blog "Neopets Fanatic" gets around 300,000 hits per month. When Chloe was 15, she started the blog out of her strong liking for Neopets, a kind of pet website. One reason why her blog has so many visitors is that she gives instructions and tips for the popular pet site.

    Then there is Tavi Gevinson's blog "Style Rookie". It is said to get 1.5 million hits per month. Tavi, who started her blog when she was just 12, puts up her photos of her own clothes online as well as designers' collections. Tavi's blog has caught on because she knows a lot about style for someone so young, and she is not afraid to try out unusual clothes or see things in a different way.

    Blogs like these are interesting, but they only become really popular after better-known websites are linked to them or they get noticed by the media(传媒). For example, Tavi's blog became an overnight(突 然的) success after being written about in The New York Times. Popular blogs can even earn money, usually from advertisements that companies pay to put up on the bloggers' sites.

    So for some, blogging is just a recreation( 消遣), but for others, it can become a source of income and even a full-time job!
