Today is the last day before the holiday, I will take the train home tonight. Recently, there is always a feeling of nothing, some depressed. There is also a new understanding of life. This society is very realistic, the size of a person's ability, determines the space of your development, technology, although it is very important, but a person's life is small, accounting for a small part. I am beginning to believe that there is a word that I have said to the old programmer.
