i glanced at it, nothing new really - bankroll management is the most important thing - and trying not to tilt - solid play will always win 'in the end' - if you can afford to play through the bad beats
I don't think there's anyone else on Youtube and Twitch that are great high stake players who streams and puts out video content of playing tournaments and cash for free. So no, I disagree with your "nothing new really" statement.
