I shall look deeper into this, as the interview is fascinating. Unfortunately for me, the example he chooses as a 'Step One' exercise is not the best in my case, as my breathing was never as 'automatic' as it should, from birth..! To me, it's a conscious thing to do, to the point where sleeping can be dramatic at times..! I'll get the book and read it, but will substitute his simple 'watch your inner self breath' with something else, such as my heartbeat (thankfully, that seems to work properly..!).
No, I don't suffer from stage fright, nor nerves when playing, but I do have the issue of being the one wanting to (trying to...) control what my limbs are doing (I'm a drummer...). Independence and coordination are a life-long path of self-improvement, and being better able to extract 'myself' from the process sounds like a smart way forward (OK, a bit late now, in my 70's, but still...). Thanks for sharing the video.
