In life, we will always encounter such and such setbacks, and sometimes we will even have a blue nose and swollen face. And it is these painful experiences that make us understand certain truths and know how to cherish them. In the same way, we always begin to cherish the emotions we once had when they are irretrievable. Too much sorrow and misfortune in life is often caused by one's own vision and low mastery.
First of all, the truth is always understood after the nose is bruised and the face is swollen. Many times, it is difficult for us to recognize our problems in good times, and it is always in adversity that we can see our own shortcomings. When we face setbacks, we reflect on our own mistakes and understand some life truths. Although this process is painful, it makes us grow and makes us face the difficulties in life more rationally.
Secondly, some emotions must not be cherished until they are irretrievable. Human nature is often like this, what you have is not known to cherish, and you can't regret it when you lose it. In our daily lives, we may be concerned about the people and things around us, and even lose our temper with them. However, when these people and things disappear from our lives, we realize their preciousness. At this time, we can no longer recover the lost emotion, and we can only be sad. 
Too much sorrow and misfortune in life are caused by one's own low vision. We are always full of craving for what we can't get and dismissive of what we already have. This mentality makes us unsatisfied, and we always live with regret and regret. Only when we recognize our own problems and begin to cherish the people in front of us can we get out of this predicament.
So, how can we avoid these sorrows and misfortunes? First of all, we must learn to cherish. Cherish the people and things around you, and cherish the happiness of the moment. Don't always complain that life is unfair, know how to be grateful, and cherish the hard-won good times. Second, we need to learn to bow our heads. Don't always look down on the people around you. We must learn to respect others and ask for advice with an open mind, so that we can continue to improve. Finally, we need to learn to reflect. In the face of adversity, we must have the courage to face our shortcomings and learn from setbacks, so that we can continue to grow.
In short, life is like a journey, and there will always be various landscapes along the way. Only when we learn to cherish, learn to bow our heads, and learn to reflect, can we truly appreciate the beauty of life. On the road of growth, let us no longer be sad because of our low vision, but bravely face all kinds of challenges in life and keep moving forward.
