Not only is that true, you have to act like it's true. In my experience, girls don't like being approached by someone who might appear to be desperate or looking to get overly attached too quickly (obviously, some are different, but you get the idea).
You always want to come off confident (not cocky), and interested. Some guys think they have to be ultra-macho or ultra-cool in order to get a girl to go after them. It's always worked better for me if you approach from the angle of a mutual interest.
Take for example my current girlfriend - before we started dating we were talking about hobbies and I told her that I enjoy cooking. She asked me what I like to cook, so I told her that my speciality is pizza.
Doe eyes "When are you gonna make me a pizza?"
You can play it like she did (she was chasing me and as you can tell, she practically had to build a sign that said "ask me out already!"). Ask her what she likes to do, when she says something that you enjoy as well, ask her a question like that.
For example, say she says she likes videogames. You do, too. Instad of saying "Do you want to play video games?" you say "I love videogames, when are we going to play together?"
You've confidently told her that this date IS happening. Now all she has to do is either work hard to wiggle out (if she doesn't want to), or set up a date.
