We aren’t competing with other women, ultimately, but with ourselves — with how we think of ourselves. For many of us, we look at other women and see, instead, a version of ourselves that is better, prettier, smarter, something more. We don’t see the other woman at all.

It’s a fun-house mirror that reflects an inaccurate version of who we are, but we turn on her anyway, because it’s easier. But we don’t need to lower the stock of other women, either for the future of the species or for our own psyches. When we each focus on being the dominant force in our own universe, rather than invading other universes, we all win.
