I feel like “results oriented” subs such as Khan St4 or Iron Throne are amazing, they really push you to get results.
The thing is, I think if you have too much crap in you it will limit the results that you can have because your limiting beliefs will collide with the affirmation.
When I ran Khan St4 last year, I really liked the results I got, but frankly, If I had done 2-3 months healing, maybe I could of had better results 
I hate healing and only did 1 month of Khan St1 which was my only healing I did here
i feel like shit when I am healing, lots of rage comes out, sadness, fear, I become an emotionnal wreck… Not a good time to socialize.
So, solitude and healing first (+hard work
), then I jump in with something more agressive.
