As a result of these efforts, I have begun to deliberately invest resources into cultivating some relationships while withdrawing from others. My System 1 self still has a pretty strong ugh field about doing the latter, and my System 2 has to have a very serious talk with my System 1 every time I make a move to distance myself from extant relationships that no longer serve me well.

There are good reasons for that ugh field. Telling people to cut of relationships for which they see no value is a hallmark of cultism. It's not advise to be given or followed without care.
