I have heard about an impressive story. It was said that an old lady drunk the old tea every day, but she had fresh tea, because she did not want to waste the old tea, so she kept drinking the old one while making the new one old all the time. The first thing for me to think about was to give up the old tea and drink the fresh one every day. The old lady presents the people who once were poor and they still lived the poor way even their life were better. If they change their thinking mode and enjoy better quality, life will be much better.
