Yes! I dont know how many times I grew up with people telling me I was lucky I was so beautiful, including my family. What kind of examples are you trying to set for your kids? Teaching them that beauty is so important is parenting failure in my book. Why not teach your kids about what is going on in the world and that there is always something you can do to help! Like the earth, only planet we have. Teach them the importance of our planet, not beauty. Neither will last forever and one is certainly more important than the other!
I dunno. A world without beauty is dismal. Beauty is incredibly important. I want my children to celebrate beauty, their's and other's. The key is not to let the ego attach to being beautiful or not. One way to do that is to view is as simply random. Some sunsets are stunning. Others are...meh. Neither "earned" or "deserved" it, it just is. Same with people.
