How can I become more extroverted?

I don't like or respect myself. I have a fear of other people and an inability to connect with others because I've been a social recluse for so long. I'm afraid of saying the wrong thing and having it come off awkwardly. I'm trying to be less emotionally stunted and become better at expressing myself. Everyone in the dining hall is extroverted. I'm literally learning to interact with people. I'm 24. I ask if there's something I could try to practice daily that would make me more confident and outgoing or just more talkative.
