The most important thing I can tell you about aging is this: If you really feel that you want to have an off-the-shoulder blouse and some big beads and thong sandals and a dirndl skirt and a magnolia in your hair, do it. Even if you're wrinkled.
I love wisdom. And you can never be great at anything unless you love it. Not be in love with it, but love the thing, admire the thing. And it seems that if you love the thing, and you don't just want to possess it, it will find you.
