     As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society,

our family, the education we receive and so on. Once this value system is set up, it's not easy to change later in

life. Financial experts say that every one also has their own belief of how to manage their money. According to

our different values, experts put us in three categories. They are: the ant, the cricket and the snail.

      The ant-works first

      Just like ants who work heart and soul in summer in order to store food for winter, these people don't care

about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when

they get old and retire. The ant loves to save but they could make more out of their money if they were willing

to invest in some funds and stocks (股票) with low risk.

     The cricket (蟋蟀)-fun first

     The cricket wants to enjoy everything now and doesn't think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have

little savings. When they get old, they might have problems. They should learn to save and buy insurance (保

险).

     The snail (蜗牛)- lives under pressure

     The snail refers to people who make life difficult for themselves. They take big long-term loans (贷款) from

the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are

not sure they can afford it. This can cause problems in the future. They should plan more carefully.
