Only by building a strong and strong "diamond heart" can one withstand setbacks and create conditions for success. In reality, some people are sensitive and psychologically fragile, known as the "glass heart". On the contrary, some people have a strong inner strength and can withstand pressure, which we may call a "diamond heart". In the face of difficulties and setbacks, we need to overcome the "glass heart" and build a "diamond heart". Building a "diamond heart" is an essential quality for us to work hard and start a business. There is a saying that the measure of a person's success is not the height at which they stand at the peak, but their ability to bounce back from the bottom. Nine out of ten, life is not as good as good. When a person is in good times, they are often able to cope with various things easily, and their mood will also be happy. There is not much difference between people; And once encountering difficulties and setbacks, how to view and cope with them depends on whether there is a resilient and tenacious "diamond heart". Throughout history, those who have been able to successfully cope with adversity and achieve a comeback in life are often due to having a strong heart. Even in the darkest moments of life, they do not give up on themselves, but are full of hope for life, turning setbacks into motivation, and ultimately achieving flying against the wind. To build a "diamond heart", it is necessary to improve one's cognitive level. I once heard a leader say a viewpoint: those who treat you well are your benefactors, and those who treat you poorly are also your benefactors. This viewpoint may seem contradictory, but upon closer examination, it makes a lot of sense. To be kind to others, to be tolerant, caring for, and helping, so that you can continue to grow; To someone who is not good to you, to stimulate you, to hurt you, to strike you, is this actually another kind of honing and urging? There is a saying that goes, "Those who cannot defeat you will make you stronger.". In fact, a person's faults and shortcomings are mostly nurtured in prosperity and comfort; A person's excellent qualities are often honed through hardships and trials. When facing difficulties and crises, people often passively leave their comfort zone, which can stimulate thinking, hone their willpower, hone their skills, and usher in a leap in life. Building a "diamond heart" requires experiencing setbacks and training. To some extent, a person's growth that goes too smoothly is not necessarily a good thing, because their ability to resist setbacks is not exercised, and they often cannot overcome obstacles and obstacles. In history, Xiang Yu had outstanding military talents and won many battles. However, in the Battle of Gaixia, he did not think of regrouping his forces to counterattack in the face of failure. Instead, he felt ashamed to see the elders of Jiangdong and chose to commit suicide by the Wujiang River. Although Liu Bang suffered repeated defeats in the Chu Han struggle, he was able to quickly recover his strength and adjust his strategy after each failure. Despite repeated defeats and battles, he ultimately defeated Xiang Yu and established the Han Dynasty. In the face of setbacks in career and setbacks in life, only by building a strong and solid "diamond heart" can we withstand the setbacks and create conditions for success. As Comrade Chen Yi once said, being a hero is easy in a situation of victorious development, but much more difficult in a situation of failure and retreat. Only heroes who have failed are true heroes. (Lai Xin She)
