Well, I started out with MM ( didn't read the full copy) and I quickly found out that MM wasn't my style at all.
To much games and routines. I'm not a smart person. I like to follow my instinct
What greatly changed my view of pick up is 60 years of challenge
I like the direct style more.... and it all comes down to this => High risk, High reward
But make sure you're able to set a frame. If you lack the confidence and lack the correct frame none of these manuals/guides will work as they are intended to work.
Start with yourself before you start on others
