I believe that nobody likes a messy room. So, cleaning up our rooms is an important part of our daily life. Though it sounds easy to organize our stuff lying around our rooms, it's really hard to do it well. First, making the decision on whether the thing is trash, needs to be given away, has some future uses or just belongs in another place is always difficult. We always tend to put most of them in big boxes for future use, but they become trash later, because we never use them again. So, before we sort our stuff, we should know what is our waste. There is a popular joke online which says that the most important thing that an old man must to do is to say goodbye to the things they actually don't need any more. They like to make a place for everything which definitely needs to be thrown away. When we finally decide to throw away/get rid of something, we need to know which are recyclable or hazardous, because there are usually four trash bins waiting for you downstairs . We are supposed to throw different kinds of trash into the correct bins.
