My great grandmother used to say, "Pretty is, as pretty does." And of course she was right. If you are acting ugly, you will be perceived as ugly. If your heart is beautiful, so will you be. This is a long way around the bush to say: The best way to feel beautiful is to do wonderful, beautiful things to others. Smile at the crabby woman at the grocery store. Pick up the piece of trash on the sidewalk, that you were about to step over. Read a book to a child. I think you get the idea. Step away from what ever it is that is causing you negatives, and spread some love and sunshine around. You'll be feeling beautiful in no time!
