First, read more books.
? Reading more books and reading good books will also change a girl. Reading more books will make a person more and more disciplined. The more you know, the more you can show this advantage in many ways, and then this person will be more confident. Maybe sometimes, you can't show it for a while, but over time, it will make a person shine.
Second, make yourself more and more beautiful through exercise and skin care.
Many girls think they are ugly ducklings, especially envy other girls, because others are like white swans, and they will never be like that. The lack of appearance will make you feel more inferior. Your appearance is natural, but you can change it later. The change we are talking about is not through plastic surgery, but through fitness and acquired efforts. If girls want to become more and more beautiful, they need to go to the gym every day. Yoga can make their bodies better, and architecture can also increase blood circulation, which actually looks more rosy and transparent. Skin care is a daily job. If you are too lazy, you will never feel beautiful. I think applying a mask will make your skin very moist and white, and women will look particularly good. Then you may change from inferiority to self-confidence.
Third, see your own advantages.
Girls should learn to look at themselves in many ways. Everyone is not perfect, and they all have shortcomings in one way or another. If they want to be better, they should learn to find their own advantages. Sincerity and kindness are advantages, and diligence and filial piety are also advantages. These will make them more and more confident. The more advantages they have, the stronger their self-confidence.
