Sun Shuzhi's diligence in thinking is the fundamental skill for work and entrepreneurship, and the greatest laziness of a person is the laziness of their thoughts. The so-called "lazy thinker" refers to people who do not actively think and are unwilling to use their brains. Compared to the "action lazy man", the "thought lazy man" has a certain degree of concealment. A lazy mind leads to a poor mind and mediocre work. As early as the beginning of the reform and opening up, Comrade Deng Xiaoping pointed out that "the more people within the Party and among the people who are willing to use their brains and think about problems, the more advantageous it is for our cause." He also criticized, "There are many lazy people in our thinking, and there are many who speak the present and empty words." Resolutely abandoning the idea of lazy people is necessary for the times and the cause, and it is also a party spirit and pragmatic style that Communist Party members must possess. However, to this day, there are still many "lazy thinkers". Some of them are unwilling to use their brains and only follow the crowd without any profound insights; Some people may not be creative in carrying out their work and will only follow the procedures step by step; Some lack the ability to plan for the long term and coordinate the overall situation, only bowing their heads to pull the car and not looking up at the road; There are also habits of implementing documents through documents and meetings, seeking only formality and formality, unwilling to do practical things and seek practical results. Learning is the "sharpening stone" of thought, and never rigid thoughts come from never stopping learning. Every party member should always maintain a humble and cautious attitude, keep up with the times, actively learn new knowledge, absorb new ideas, and understand new things. By reading "books with words" well and thoroughly reading "books without words", one can truly achieve the goal of thinking, understanding, and gaining from learning, constantly improving their quality, expanding their abilities, and enhancing their abilities. They strive to overcome the dilemma of being lost in knowledge, blind in knowledge, and confused in ignorance. Think wisdom, think methods, and think abilities. Every party member cannot become a thinker, but they can definitely become an active thinker. We should closely combine our work reality, consciously apply the Marxist standpoint, viewpoint, and method, study new situations, solve new problems, and respond to new challenges, practice the skill of clearing the clouds and seeing the sun, hone our ability to excel, and be busy but not chaotic, busy but not confused, and busy but not tired. Ideological backwardness is the most terrifying backwardness, while conceptual backwardness is the deadliest. The most terrifying thing in the world is not failure, but self imposed limitations in thought. When our minds are fixed, it is very dangerous. In the face of tomorrow's war, we need to timely break away from conservative concepts, conservative thinking, and conservative thinking, dare to think of what our predecessors did not think of, and do what our predecessors did not do. This not only breaks the fixed thinking pattern, but also does not violate the law of innovation. We should take the initiative to take action without deviating from the actual situation of the army, support our winning ability with innovative ability, and prepare for tomorrow's war with a "braver mind".
