Part of what I am writing here, I learned at youth group.
The value of you: It's not what you have, where you live, or the clothes you where, or even the money you or your family has. The value of you is who you are, the person God created you to be.
Think about this: All of your belongings have been taken away, how many of your friends now would still be your friend? Make friends that you know enjoy you for who you are and not what you have.
