How to talk to a guy that you've never talked to and really like?

[Kk]

So I really like this guy we are both 20 years old. He sits next to me in one of my classes and I kinda fell in love with his personality based on what I've seen so far and I really want to get to know him more. The was he looks is so cute! It's definitely the look I go for! And he just an all around great guy from what I see... I never really talked to him but I want to! His twitter came up under "people also like...." When I followed one of my friends... I was gunna follow him on twitter but I don't want it to be awkward... And I'm really shy so it's not like me to just go up to a guy I like and start talking to him!...What should I do? Forget about him or try something? No sarcastic answers please!!
