More than 90% of people or enterprises spend every day in contradiction. What is AAK Hydraulic Valve's view? Today, I want to make a plan, whether it is the marketing of hydraulic valves or the innovation of hydraulic valve production process. This is a definite action, but after the action is done, is it sure that it will pay off? This is a contradiction. More than 90% of people spend every day in this similar contradiction. More than 90% of people linger in contradictions. What to do on this day? Do certainty, uncertainty, or other things? But there is only one most important thing every day. For example, according to the short board theory of a wooden barrel, the height of water that a wooden barrel can hold depends on the shortest board. Should we make up for the short board immediately? Some people say that instead of making up for shortcomings, we should focus on the long board, do what we are best at, and do it easily. Who should we listen to? More than 90% of the people spend the day in contradiction, so do I. In fact, people are most vulnerable to the herd effect. Many of us deal with things every day in a perfunctory way when we go to work. At least 70% of us deal with it perfunctorily. This is because we are not active. In the hydraulic valve factory, for example, what steel has not yet arrived, what equipment is good, and what requirements are so high, his mind is always passive. Or, these passive ones occupy 70% of his time in a day. It's easy to be at a loss when you deal with the current things perfunctorily, it looks like that this is right and that is also right. You also want to do something actively, maybe you can start to do a little, but you can't persist, and then go back to the old situation. If people have knowledge but don't take action, then this knowledge is just bragging. Maybe it has flattered society, but people themselves have not improved. Then they feel good about themselves, which forms this strange circle. How can we break the circle? In AAK hydraulic valve, I cycle myself, practice and construct my hydraulic valve system again. One is practice and the other is hydraulic valve knowledge. Practice is hands-on, such as writing tweets and taking videos of hydraulic valves. From materials, equipment, process, technology, production line, quality inspection, pick it up again and go again. Although I am also in contradiction, I will rebuild the knowledge system of hydraulic valves in a cycle and go through another cycle. What are the advantages of this? Reconstruction and circulation, improve the brain. Practice should be consolidated, not to extend one's own knowledge, but to cycle knowledge and change the neural law of the brain. For example, in the practice of hydraulic valve system, write tweets, write every day, rebuild every cycle, and recycle every cycle. What is the essence of "Skill comes from practice"?
