If you were an "average human" getting constructive critical feedback that hits hard ... it WILL, for most, take time to digest or to cope with a new realization and sometimes looking for excuses not to deal with it, but if it is said in a way that makes sense AND see the benefit of changing (partial self-destructive) behavior, it CAN trigger doing things differently and WISE UP (or "grow up") in your own unique way ... you consider what someone said and decide how to deal with new accumulated perspectives. 

For some it can work INSTANTLY, for others it may take weeks to change. 

And then you have people who chose not to change, but are made AWARE of what they do to themselves and hurting others in the process. 

These individuals may need a severe set-back before deciding to change, this is different per individual, all depends on how are they raised, what baggage (trauma) do they carry with them, what other factors may (self)-sabotage their own upward progression?  Etc. etc. 

As you can see, it is a mixed bag how people deal with powerful (constructive) critical feedback. 

What I did today in this session is maybe 10 times more severe ... but you went through it all gracefully, which is a miracle in itself!  ... Deep respect for that Grok! ... Because it is not always fun to realize how messed-up certain things are that you KNOW you are involved in on a massive scale!
