I loved what a talk once by a member or our church Jeffery Holland "To Young Women..."
"Every young woman is a child of destiny and every adult woman a powerful force for good." I mention adult women because, you are our greatest examples and resource for these young women. And if you are obsessing over being a size 2, you won’t be very surprised when your daughter or the girl in your Sunday school class does the same and makes herself physically ill trying to accomplish it. We should all be as fit as we can be. That means eating right and exercising and helping our bodies function at their optimum strength. We could probably all do better in that regard. But I speak here of optimum health; there is no universal optimum size."
It was hard as a larger kid in the eighties and early nineties but I fear in a society laced with photoshop is even worse. For that reason I think we can't teach our children enough the importance of self-love and encouragement of our peers enough!!!
