Meeting a new social group?

Quite honestly, I'm tired of my friends. Not that I don't like them anymore, but I just feel i've grown to be too different to hang out with them anymore. I find them immature, and more importantly uninteresting. They do the same things day and day out, and I just get really bored with them. I want to completely abandon the people I know now and jump into a new social group. What are the best ways to do this? I don't want the new people I meet to be associated with the people I currently associate with (for no reason other than I KNOW that it will start drama if both groups are in contact) Also, when I go out and try to meet this new social group, i'm going to be doing it alone since I am trying to abandon most of my old ties.
