Why is insight often useless?
I've had a lot of insight which seems valid but changes nothing. I'm not just talking about something seeming important and maybe revolutionary when it first comes up. Even reading things I wrote many years ago can be impressive.
Yet, practically none of those things actually led to improvement. They're just analytical observations with no power to do anything.
My best guess about this is that there is a system of emotional limitations, and trying to "rationally" apply such insight would be breaking that system of limitations. This seems very rarely recognized. People recognize if something is physically impossible, or someone doesn't have the money to afford something, but it's as if emotional limitations don't exist and people should simply behave rationally. I guess the closest I've seen to an acknowledgement of this is protectors in IFS. You could easily claim that what a protector is doing isn't actually practically useful in life in terms of rational material goals, but it can have an important psychological purpose.
So, then the question is: how can insight be useful? Why couldn't I figure out the freedom I actually have, even with that system of emotional limitations?
