It is a recognition of my own mental limits.
To be frank, this does not answer my questions, which were not accusatory, btw, but rather a way to establish what we are actually conversing over so as to better communicate. Nyire didn't answer my questions, either, but instead tried to put me "in the hot seat" by asking more. So far, that is not practical or logical for
me.
For now I will say that's fine because if it's not you or Nyire who are truly interested, it will be a message in a bottle. I think the most important part about your question regarding practicality -which I agree with, btw- is ...
practical for whom, exactly? You, or me? Or in general? I will start by saying that to a large degree we have to find our own practicality daily. How can I make it practical for you? Probably I would ask you to do your scales

. We'd work things out one step at a time. That's what makes things practical; step by step.
Or, are we talking practical for me? Do people think that I may give some kind of statement that they consider impractical, illogical, broad ... and that this means I'm not thinking critically and studiously about my daily work? My mind boggles to think to try to explain how I make these things practical to my daily life. At the same time, I consider that very question quite often. Ah gawd, where to start and where to end. I should be asleep right now.
All I can say right now (sorry, super tired), is that I have a concept of how to organize every note, and that I have been searching for that. For me to gain a concept of a principle gives me a vision to aim for, a standard to work with, and a tangible application. But, it takes very much time and effort. It is an actual, honest labor. Sometimes I have woken for months in a row at 3 am in search of this, and working at the piano ... I have very little social life and I've had to fight very, very hard for every single morsel of piano life that I have, and have faced a willingness to literally lose everything from my life so as to continue my studies with my teachers ... there's loads more ... but I'll leave it there and say, if a person can come to me with a similar story, THEN feel free to ask me about my "logic" since they are very connected (do you see the logic in waking at 3 am for months in a row? For being willing to foreclose a house? Divorce a spouse? Lose family and friends? Even sell a most precious piano, all in order to keep studying?), at that point ask me why I find practicality in the things I write here and how that relates to a music and single notes.
I hope I don't sound rude and I can feel that I am probably too tired to be writing. The disclaimer needs to be that I don't claim to have all the answers ... still lots to learn.
