What attitude should we take to money

In morden society, the economy is developing fastly. Money which is used as a tool is becoming more and more important for us to live in the society. So many people think the money is the source of happyness.
I think this attitude is wrong. Happyniss include many elements . Money is not the only and the most important element of happyniss. In morden society , many people consider the money as the only element to the happyniss. I think money have the influence of happyniss, but it can't be the only element and important element. The true happyniss include many elements. the money can only have a little work. So the money can't be source of the happyniss.
I think the money only is a tool for the society. It can't be the source of something. It can only have a little influnce to something. So we should take the money as a tool not as a source of something. There are many elements to something and the money can't be the only element.
