Yeah, I guess I'm more addressing those Type-A personalities who might be reading this thinking "I'm gonna go do this and kick ass, taking the practice to the maximum limit my mind will let me"... then going in and ignoring their pain through sheer willpower then coming out in a lot of trouble.
As I knew there would be sitting with determination later in the week, I trained my body and mind in the first days by sitting still as long as I could.
