Interesting, Mick, re 'the ex marine', referring to the Jocko 'Good' vid. Everyone has their own take but IMO, Jocko is one of the last folks on earth who would likely be labeled as promoting artificial happiness. He's been deep in 'the shit' many times over and the current leadership seminars he runs are based on what worked and what didn't work re leadership and attitude under some of the most brutal conditions and scenarios available to the human condition.
That's my take anyway. You should check out some of his podcasts, you might enjoy something there, he has a lot of traction with a lot of folks
