In my opinion, if you want to improve, you have to play/practice (as if it were a sport), and what's most important, it will most definately be different for every user, so trusting other eoples' reviws is not very.... informative
I do play quite often, and that's what led me to look further into this. I've been reading up on it and just figured maybe someone here had given it a go and wanted their opinion the experience. Either way seems I'm not going to find it, so I may wait until one of the cold months with a light workload, and buy access for 1 month to try it myself.
In the end it's an endless cycle of trust and lick tbh. It'd be your luck if you improved based on his teachings but if you already know everything he taught, thats just bad luck.
I know I don't know anywhere near as much as they are teaching, just from watching and digesting the free content out there.
