Bored with my social circles

Do you ever feel that you are just surrounded by the same people all the time? I was thinking the other day, and realized that I really don't have an opportunity to meet a lot of new people because of where I am right now in life. Same people at work, same people at church, etc., etc. I think I need to do something where I can meet some new people, but I don't know what that is. Any thoughts?
