Too nervous to talk to very pretty girls?

Why is it that im too nervous to talk to very pretty girls? In my mind I think they are better than me and I dont deserve to come in contact with them.. Like this girl across the street is very pretty but too nervous to talk to her

go talk 2 her take a chance
it will pay off
girls like it whern you talk to them
they think you are outta there league
so just go talk!

just talk to her... Start off my just saying hi when you see her then move towards asking her how she's doing ask about her interest such as sports... Don't talk about yourself, if she's interested shell ask... And lastly be confident, she's not better than you in anyones eyes just your own good luck

confidence.
Just saii like heyy.
and talk to her in class or somthingg.

HEY,
well I think you should go talk to her and see how it goes I mean life about taking chances. just start off by introducing yourself to her and see where it takes you from there

ok ill fill you in. I myself know that guys are scared to talk to me a lot of the time...we girls sense these things. a lot of the time "prettier" girls go out less on dates because guys are so scared of them...and when a guy does pucker up the courage to talk to us he gets extra kudos, because we're used to doing it ourselves most of the time...so take a chance! I bet you won't regret it.
