Since prehistory, human being have been using something to exchange the things they have to get the things they want, for example, they exchanged meat with rice, or maybe they offered some services to get some food, actually these practices still happen until now. But now, we can use money with different value to get things we want.
The concept of money has been helping peoples in doing transaction. We don't have to bring such a big things to exchange it with our need, just bring a sheet of papers and we can get something, whether it goods or services. Now technology is getting better and faster, money has different shape or money has been upgraded. Now we can use credit card or internet banking to do some transaction, instantly and efficiently. So Money nowadays nominally has higher value but physically has a less value. Because money is a tool for economic transaction and human is an economic creature that is why money is very important factor in today's world, without money, it is hard for us to get what we need or we want. Peoples also struggles and compete to get money as much as they could, that is why money also considered as a root of problems in this world.
We cannot deny that we need money in our daily life need, we can use it as a tools and motivation to get a better live, but we also shouldn't put it at the first position in our life, because it can bring disasters in our life. As goes the saying : " dont ever underestimate the power of gold" which means , if we love money too much the bad thing will happen in our life.
