I've been lurking here for several years and already internalized a lot of ideas, but I want some more information about frame and how to practice the art of holding frame.

Can someone suggest books or something practical? My major problem is boundaries(a lot of progress, but sometimes I can't properly handle some new situation which never happened to me before). Also, it's sometimes hard to me to ignore trash talking from my friends or colleagues(although it perfectly clear for me that when I don't react and completely ignore it they respect me more).
