Movies are great. I love the movies! But just like 90% of everything else that has to do with Hollywood, the way love is portrayed in the movies doesn't exactly translate into real life. It's harder for the nerdy guy to get the girl in real life than it is in the movies. In real life you don't have Transformers to help you out! What kind of girl wouldn't date the guy that was friends with Optimus Prime!
For the guys left to live amongst us mortals I can see how getting the desired girl can be difficult at times. The biggest mistake guys make in chasing a girl is letting her know you like her too much. I know, sounds ridiculous but it's true. Ever heard the phrase, "want what you can't have?" It's true, and we all do it. Men and women are guilty of wanting what they can't have. So do you know what this means?
Become desirable. Yes, be the thing that she wants and thinks that she can't have. Of course this is only going to work if she knows that you exist, so let's start there. When you talk to the girl you like don't be desperate, compliment her too much, or give her too much attention. You might be surprised to find out how many women fall in love with their guy-friends.
Be the guy that she can come and talk to, be positive and funny. Show her the "real you" without letting on that you're into her. Women don't like to admit that they're attracted to the guys that make them work for it. So make her work for it! When you guys hang out don't be possessive over her or fawn over her too much. Make those suttle connections lightly touching her arm, hugs that last a little longer than just "friends", holding her gaze in a smile.
After she's noticed she has feelings from you the ball is in your court. It's up to you to decide where to go from here. To keep her interested in you continue to have fun together, and never forget to smile! Smiling is one of the best things you can do for yourself, they're contagious. A confidant man that can make a girl smile is invaluable. By the time you're done with her she's going to rip other girls' hair out just for looking at you!
