You can't imagine anyone practices after they leave,and certainly not enjoy the practice, I wonder why that is, I bet you've even got this concept that it wouldn't work without gm, can't imagine where you got THAT concept from. Too funny.As I said to you the other day, don't give up the day job.
You may well get a lot from your practice of knowledge, but you sure ain't getting much psychological awareness from it.
As for getting it all back without the concepts, duh, why do you think some of us left?
