(1) Everyone has individual differences in the speed of physical and mental development. Some people are fast, others are slow, as long as they are healthy, it is normal. Paying attention to nutrition and exercise is helpful to growth and development.

(2) Paying attention to one's appearance, clothes and grooming, and caring about appearance is one of the characteristics of adolescence. Proper dress can exude youthful vitality; But spending too much time and money to be unconventional is likely to waste youth. Because the neat appearance and elegant manners are the places that really attract others.

On the one hand, teenagers prove their uniqueness through different channels, on the other hand, they are eager for everyone's acceptance because of their strong sense of belonging. Therefore, they will feel unknown. Proper self-understanding and enrichment, more attempts, experience groups and good interpersonal relationships can all help you develop a unique and healthy self.
