It's actually a question I used to ponder when I was on the dating scene.
I hate to say it, but the answer I came up with was that the younger the woman, the more she had to offer a traditional man. If you truly are a traditional man, by which I mean a man who takes care of business, prefers action to complaining, keeps opinions to yourself until you get to know people, and approach women with an attitude of respectful protectiveness, the woman you are looking for may be the woman you are looking past due to her youth compared to your own age.
If you live near a college, I recommend you either get a job there, or better yet, take classes there. Who cares if you need the classes or not, take freshman courses like a foreign language 101, or something that interests you.
