Characteristic to change

A characteristic I would like to improve over the course of my college stay is to become a little more outgoing. College I think is a perfect place to try and make this change, because I am constantly around people and I don't really know any of them. It's a good opportunity to meet new people and to do that I need to be more outgoing. I don't want to just be more outgoing around friends, but in the classroom as well. I would like to get myself to become more active in class discussions, which is something I did not do much during high school.
