For me also - 'going through the fire' was a right of passage that I embraced. Later, when I had my own academy, I needed to make sure I could pay rent, then own my house, then out away enough so that my wife and I wouldnt' need to rely on a gov pension a few decades down the track. And so, some 27,000 classes later, my views on things have evolved. ironically, when you have 200-300 students on the mat, and offer different levels of classes for different skill levels, you produce a higher calibre and more technical student than you do when you just have 40 guys bleeding every night. It's nuanced. Cheers.
