Is it normal that I don't understand why girls like confidence?

I figure that's mainly why most women want a confident guy, cause they want someone to make the first move. I'll admit it sucks, and I kind of wish that sometimes I didn't have to do it. But I'll agree that someone who puts themselves down a lot would suck, then again I've been told that I do a lot. But I think it's cool that you find shy guys, well cool.
