I think we're all shallow to a degree, so it's fairly normal to be shallow.

You just have to reason through it. For example, you said that you only date women for their looks. Look what happened when you dated shallow women like yourself. It never worked out, right? Ultimately, personality WAS important to those women because they didn't feel a connection with you. So even though they were shallow, they weren't too shallow after all. They wanted to find their soul mate, someone who they could spend the rest of their life with. Looks may have been their #1 requirement for a guy, but personality was just as important to them.

So it's important that you find someone with a personality that matches or is similar to yours, because personality does matter to other people. Besides, you don't want to feel lonely. You want someone to love you and be with you. The only way you'll find someone like that is to find someone whose personality connects with yours.

It's okay to be concerned with looks, though. I think most people are lying when they say looks aren't important. But instead of focusing on finding the hottest girl, settle for good looking and see if her personality is something you like. You'll be much happier with a good looking girl who has a nice personality than the world's hottest girl with a horrible personality.

If you see a girl who's dressed in gothic clothes, has piercings everywhere, and covered in tattoos, you may or may not like that. That's okay if her looks aren't your personal taste. You can pass up on that girl. You're allowed to have personal standards. Just don't set your standards so high that you limit your dating pool to the top 1% of hot girls.
