Sure, dating can be frustrating, even disillusioning. But don't let it get you down. If you're feeling negative, you'll scare off the good ones. Get out, meet people, and be open to new people and new experiences. You'll meet someone. After all, dating is a process of elimination—you just haven't met the right one yet.

"I think some people are much more rigid or sure about what they want," says Schwartz. "They don't want to make the same stupid mistakes. But feeling jaded, that's a self-invented problem. There are many good people out there. If you have a 50-item list of criteria, if you're too specific about what you want, too rigid, you're going to find yourself alone forever."

Her dating advice: Look beyond the bald head and other imperfections. "Have an open, optimistic mind. You've got to have enthusiasm, imagination. I know a 50-year-old woman who thought she wanted an intellectual. But she met a cowboy and is having a great time! When people say they're cynical, jaded, they're really scared of having to change a little bit."
