Self-esteem is a complicated issue for everyone. In teen years, there is a lot of worry about how teens look and what others think of them because of how they look. Usually, kids are much more worried than they need to be. It is important to take care of the basics like making sure you are clean, appropriately dressed and, well-rested and well nourished. Beyond that, clothes and hairstyles can help you feel like you look good. The biggest factor in what others think of you is how you treat them, if you are friendly and kind. Others, even teens, respond to how you behave and how interested you are in others.
