When you look in the mirror, you sometimes think that you need to change something in yourself. You would not mind having empty hair, white teeth and being more muscular. Teens feel this way often because they grow and their appearance changes. Speaking of appearance, the body matures and it draws attention to you. You compare yourself with friends. Girls often gain weight, and boys' shoulders become wider. The media influences your self-esteem. Programs show ideal people, and you start thinking that something is wrong with you. It puts pressure on you morally and you become obsessed with proper nutrition and exercise. However, advertising sells dreams, not reality. Your classmates do not notice every pound that you scored. You need to be confident, not a thieveslavnogo and focus on the things that you love about yourself.
