What was the past like?

The past is: what I desperately want to remember is gradually blurred, but what I desperately want to forget is as clear as yesterday. Life is like this. In this world, few people's lives can be realized step by step according to their own ideas. There is no need to do everything as they wish, otherwise it will only be much ado about nothing. It used to be the same. The past is not dispensable and can be imagined. The past is an existence of the past. Its existence is independent of personal will, and it is not up to you to remember or forget it. I can't remember what I remember, and I can't forget what I want to forget, so let it be. The past is: only the aftertaste can't be reproduced. Yesterday reappears, written by carpenters, makes countless nostalgic people deeply miss it and fantasize that yesterday reappears in a sweet melody. Times have changed, and things have changed. In fact, it is not yesterday or the past that reappears, but the memories and feelings that you have never forgotten. Even if you are still you, he is still him. Who can say that you are still yesterday and he is still yesterday? People can't step into the same river twice. Time is like a river. Water will not flow backwards; People can only move forward. It used to be: I can't catch it but I can't let it go. Not everything can be as expected. Many times, what you can firmly grasp in your own hands is extremely limited. After all, the world doesn't revolve around itself, and even people always think that "under the sky, is it the land of kings?" Isn't it time for the emperor's old son to have power and influence? If you know you can't catch it, you shouldn't chase it down and try to reverse it. Let it go. Knowing when to let go is not only a relief, an attitude, but also a kind of happiness. The past is: the track of life is the accumulation of heavy degree of life. Everyone's life is a layer upon layer accumulation of the past. Without these accumulations, life will lose its thickness and eventually return to zero. Coming into this world is really a waste of time. Inadvertently, the past will be divided into several levels: unforgettable, influential, scarred, broken, beautiful and warm, affectionate, hateful, irrelevant ... each level is an integral part of life, but its influence on thickness is different. In the case of limited life length, what everyone should do is to extend the thickness of life as infinitely as possible. The past is: all kinds of experiences that can't be completely controlled by yourself. What has been experienced is not necessarily a bad thing, and what has not been experienced is not necessarily a good thing. Once a thing of the past, no matter how good or bad, you should learn for yourself. Because the past is not only used for touching the scene and nostalgia, if it is limited to this, then the past has become a unique patent for petty bourgeoisie feelings and sister forests. In fact, the past is just a memory left in my mind. Some unforgettable, some unbearable, and some desperate looking back. Either way, the past is not like smoke to everyone. It is not like lighting a cigarette, taking a deep breath and curling light smoke. Despite several struggles, it finally failed to meet its fate and soon disappeared into the air. After a while, even the smell disappeared as if it had never existed. In the past, even though those vivid images have disappeared and the joys and sorrows have been blurred, the taste and feeling are rooted in the heart, invisible and intangible. Just when I think about it, it will stir all the sprouted, green, withered, scattered and muddy leaves on the vines in this life.
