Nowadays, some people think that money is everything. They think money is the most important thing in the world. They believe that they can get anything with money. But I don’t think so. Although money can buy a lot of things we need, there are a lot of wonderful things in the world that can’t be bought with money. For example, knowledge can’t be bought with money. One can’t be rich in knowledge unless he/she studies hard. And as everybody knows, time can’t bought with money, either. No one can turn the wheel of time backwards. Once it goes by, it will never come back.
