What, are you in midlife crisis again? Don't make any decisions now!
I actually have no idea how that relates to what you quoted, but, no, not that I know of. Though, my freak out on Sunday was perhaps a condensed version of one (but was also related to the fact that I personally needed physical, mental, and emotional space that I didn't have at the time because of certain circumstances).
The change to a performer mindset is a large one, and almost unique to piano.
I came to piano as a performer and never considered any other approach. It took me a long time reading posts on this and other forums to realize (though not fully understand) that most pianists consider themselves students or hobbyists and many never intend to play a single note in public for anybody besides a teacher. That approach was very alien to me but appears to be common. I doubt if any other instrument has any significant number of players who do that.
I don't know that this is true, regarding the change of mindset to performing being unique to piano. I mean, there are plenty of singers who take lessons just to sing better for their own purposes, and not necessarily to perform. I think that's true for many guitarists, as well, and I would imagine that's true for numbers of other instruments, though I understand that for some it may not be as musically fulfilling to play as a solo instrument (like the flute, maybe?).
What I mean is that I think it's important to clarify a separation between preparing and practicing a piece vs. preparing and practicing a performing/performer's psychology/mentality. I think the performer's psychology/mentality is fundamentally unique to itself and is rooted in a basic desire and ability to communicate, share, or be with people, etc.. For example, it is one thing to sculpt in stone or clay exactly what one needs to express through the sculpture, and to make it as true to the idea as possible, and then it's yet another thing to decide to show it and share it. And, while sharing it might be a goal, sculpting a perfect line in general doesn't necessarily sufficiently cope with a psychological fear in eventually sharing the sculpture, as that fear is ultimately rooted specifically within the psychology of sharing and must be dealt with, at least in part, specifically within that realm. Or let's say, perhaps one is perfectly capable of shaping a perfect line, but the fear of sharing (once the sculpture is done) prevents one from ever forming that perfect line even in private, and therefore, even though the sculptor is ultimately capable of shaping it, never does because s/he can't separate a fear of sharing from the ability to shape in the first place.
Practicing something a thousand times just because there is a fear of performing, doesn't necessarily "handle" the psychology of performing or create room for a pianist's/musician's true ability to show during performance. There is a point in preparation where one must realize they have actually accomplished what needs to be accomplished, and to stop trying to deal with the psychology of performing through repetition of passages ... especially if there is a psychological barrier rooted in performing which is hampering a person in preparations.
hmmm ... that's still a crude attempt.
