To do this, there is a step-by-step process, that is, studying things (studying the boundaries or boundaries of things and understanding the whole picture of things), knowing (knowing the ins and outs of things, knowing what to do first, then what to do), and being sincere (because of knowing, the mentality of being smart and lucky is gone, and the illusion is retained. Doing things will be more and more sincere in the original intention and heart), right (gradually get rid of resentment, happiness, fear and trouble), self-cultivation (right will reduce all kinds of paranoid prejudice, and will not be blinded by love, meanness, reverence, pity and laziness, which will affect the accurate judgment of things), family (after right and self-cultivation, the last few can be far away from us, and I don't need to say more. To sum up, to be a gentleman, you need to do a good job. Through learning (learning from things), constantly correct your heart and cultivate yourself. On this basis, gradually lead a family, govern the country, and be wise to the world.
