"Looking back at history and looking forward to the future" is a warning that is often mentioned. More often, it is our slogan to express an attitude or position to the outside world. It seems that there is a sense of worrying about the country and the people, and it even has a magnificent momentum. Looking back at history, we can see the footprints of predecessors, the contact and interaction of people, things and things in history, the details of history and the progress of history. At the same time, we can zoom back to ourselves, and we can also see the hardships, tribulations, choices, joys and sorrows, failures or successes we have experienced along the way. In the face of every choice in life, what kind of thinking and measurement have we experienced? What kind of choices have been made, what kind of results have been obtained, and what kind of life course has been created. Looking back should not stop at looking back, but also consider that the past is the reason for today, and today's choice will also be the reason for the future. Looking forward to the future is not a dream out of thin air, but based on the past and present, tracing back to the source, reflecting on the growth process of roots and exploring the possibility of the future. From national development, social progress to personal life, this sentence should not be just a slogan, but an empty talk that sounds bloody but I don't know why. How many people who shout slogans don't know anything about history, or just have a little knowledge, and regard history as an antique that has nothing to do with the present and the future. They just think they should stay in the past and enjoy it once in a while. Even my own life path was forgotten afterwards. I forgot my original intention, forgot the purpose of my original departure, deviated from the direction I set, and left in a hurry without knowing where to go.
