How do i make more friends and get people to like me?

[Sam]

I am quite shy and i get nervous when going up to someone i dont usually talk to and saying hi. I have a couple close friends but not many. I will often start the conversation on facebook with a variety of people. I act nice and take an interest in what they have to say. Though no one ever will start the ocnversation with me on facebook. I dont know what to do so people will take more of an interest in me.
