I am going to say something totally non-PC, and I apologize for that. Find a bunch of people you would consider not very bright (from your POV) and do your best to hang out with them at all cost. I can't totally put words on it, but it seems to me the more "brainy" your daily thoughts, your social circles are, the more you are at risk of losing your instinct for social relationships... and the cure is to be realeased in the "wild".
