Teens: How to Feel Good About Yourself?

I use to feel that way all the time was really becoming a problem. Due to this, I was left on the sidelines looking at everyone else have so much fun. By the way, I am 15. At times I still feel that way but you should not let it get to you. The problem is you have low self-esteem. It is okay to get a lower grade than someone else; you can not be perfect.

To begin' try saying hello to others at school you would not normally talk to.
