Reading is not necessarily reading a self-cultivation book, as long as it is a good book, it can improve self-cultivation. Read more biographies of celebrities and historical stories. These books are of great help to improve one's self-cultivation, that is to say, the more knowledgeable people are, the better their self-cultivation. But it is not absolute.

External image, mainly words and manners, dress. Don't pursue image quality too much ... to sum up, it is a few words, clean, natural, comfortable and decent. This kind of comfort is comfortable in the eyes of others. Don't imitate it deliberately. Some fashionable clothes are not suitable. Clothes make the Buddha depend on gold, and choosing what suits you is the most important thing.
