So i'm in a conundrum. As of late, I been slowly realizing that I'm growing more and more disinterested in the group of friends that I hang with. I feel bad because they've done nothing wrong, and I really don't want to stop hanging out with them. I'm just past the point of wanting to go out and get drunk ALL THE TIME. I'm going through a phase where I'm trying to better myself as a person in various areas, and I would like to be around like minded people. My current group of friends are wicked fun, but they don't stimulate me mentally. Any suggestions on how I can maintain my current friendships as well as create a "mastermind" group so to speak? P.S. My interests are philosophy, travel, and quantum physics if that helps.
