Humans have evolved to this point, although they have lost the agility and lightness of flying left by their ancestors, but they have gained a pair of spiritual hands. Although autumn has lost its colorful splendor, it has gained maturity and harvest. Although the old tree lost its youth, it gained rings. Although dandelion lost its body of life, it also left the seeds of life flying far away. What you gain, you lose. Gain and loss are the unity of opposites. We have gained something when we lost it, so we don't have to feel dejected for what we lost, and we don't have to be complacent about what we got. The price of loss may be gain, and we can face every failure calmly. Countless wounds are given to us by life, because every wound marks progress.

Edison spent ten years and after about 50 thousand experiments, he transformed the corrosive copper-sulfuric acid battery into a storage battery. However, when the experiment failed 9000 times, his friends advised him to stop working and give up the fruitless experiment, but Edison said, "How can you say there is no result?" At least I know that there are 9,000 methods that can't be used! "

Edison faced failure frankly, and it was his previous failure that made him succeed later. Edison gained experience and lessons from failure, and succeeded with his perseverance. What you get will be lost. Only those who have failed know the secret of success in life.

Everything is the same, gain and loss, loss and gain, just like a pair of brothers, although they don't get along, they will always be together. Losing may mean getting, but getting doesn't mean losing?

After several generations of construction, the great wall, a huge project, played a certain military role, stopped the biting wind and rain from other ethnic groups and prevented the northern barbarians from being conquered by iron fighters. However, it also annihilated the desire of exchanges and integration among ethnic groups and blocked the pace of friendly coexistence. The Great Wall is both a protective wall and a separation wall.

Face up to the gains and losses, understand that gains and losses are innate, and life has two sides.
