Please help, need suggestions and ideas

Guys and girls please help. Well I have a crush on this girl. I have talked to her around five to six times and I think you can call us friends. But I am getting tensed while talking to her. I am even not able to bring out topics to talk on. My mind goes blank. My voice is also a bit low ( am not used to speaking loudly. Am A shy guy) . So my voice also gets tensed up and I screw up big time. It is bringing my confidence down and I feel like she will never like me. She is a kind of a girl who iis famous, and got lots of friends (guys also) . But I want to be the one for her. How do I impress her. Let her know how awesome I am in certain things. How do I make our friendship better? How do I make her blush if she thinks of me? How do I start up conversations and talk nicely without getting tensed?

You should make it so you two are in a casual place. That way you both feel comfortable and are more relaxed. Also have a since of humor, girls love that.

What do you like about her? Is she intelligent/generous/funny? Does she dress-up always or is she simply-beautiful? Does she have goals for her life that you find interesting or maybe similar to yours? Women like to be "liked" and found "interesting" Women are impressed by a guy who wants to know about them and then remembers that information putting it to good use in future conversations - so if you're looking for a topic, the topic is HER. Don't ask her a million questions, just choose things you genuinly want to know about her that you feel you can contribute to with your own stories. It is important for you to remember that you have only talked to her a handful of times and you are still in the stage where you should be deciding whether SHE is the one for YOU - not the other way around. Thats where your confidence will come from.
