Girls: How to Approach her?

[Jmt183]

Ok so in my college building, Their is this girl that i want to talk to but i truly have no idea how. I've never talked to her before so we don't know each other at all. I'm kinda nervous, i don't want to look like some weird a.s.s creeper who came out of nowhere and started talking to her. After i start talking to people its easy for me to open up and be funny. The hard part for me, is approaching them. Any suggestion? or Advice? i really don't want to look creepy lol
