I always go on about Models because it's good.
VH1 series,The Game, Mystery, Secrets of aLpha male, la Ruina, David Deida etc.etc lots of stuff went in
RSD- particularly bad for making you act weird.
I'm far from prolific and still want to improve ( that's why I'm still here)- the only material I saw definite results from and started to feel really good about what I was doing was Models.
