Have you ever thought you were not good enough for someone?

I often come across females that are so beautiful. Sometimes I wonder what type of lucky guy is dating her. I want to approach them but I am often intimidated. People say someone that good wants something just as good. Which is a bad way to think. After all not all females are like that. I know many that come of as superficial but they are really not. They are cool and down to earth. These ones I went to school with or are close friends with. I often feel this way due to my financial status. I have a decent job that pays $400 a week. Still living with my parents at the moment and have no car.
I am not saying this is what all females look for in a guy. However at age 26 having my own place to bring a girl to would be nice. Don’t want to take her to my parents house, it feels wrong. Having a car would be great to go out with. These are things I am working on acquiring soon. I know a lot of females who say confidence goes a long. I guess that is something I am lacking. I often come off as shy & quiet. I am just a really chill and laid back guy. Also I guess I should not look at just the outside. I know many females who are beautiful, but that is all they have to offer. Which is their looks. I guess I should not look at just looks. But get to know females a bit better. At the end of the day, I am saying we all may have someone who we felt was too good for us or out of our league.
