Background summary of article: The article states that truly effective results can only be obtained through practice and not through sheer theory. A guitarist who does not focus on his rough spots will still have more or less the same quality tune. Anyways, I liked it, as you may be able to tell below.

Practicing
As a pianist, I found this article especially meaningful. Many of my practice days were in reality playing days, where I would run through a piece and simply enjoy it as it was. However, these were not especially productive, because although I ran over the rough spots a few times in my play-through, I never gave them the concentrated steam rolling of “spot practice” needed to truly smoothen them out.
I found the “measurable improvements” part a bit vague though, because it seems many times after a practice week, although I feel more solid, the piece sounds very much the same. Undoubtedly it would be better if I simply recorded the piece at the end of every lesson, and made a chronological sequence of the music over weeks of practice, analogous to excel spreadsheet of sorts—perhaps I should do this.
In the meantime though, satisfying myself with “persevere and success will come” is a tall order to me. That was supposed to happen on polysleep, and certainly I took it to heart, but by week 4 (albeit with missteps that probably had disproportionate impacts), I was growing frustrated with sheer perseverance. I was sleepy and waking up from 20 minute naps was not amenable, but compared to my normal sleep results, how different was it really?
But now a thought occurs to me (or rather a lurking thought has stepped forth boldly) and thinking back on it now, I am critiquing perseverance on faulty grounds. It was the design of the experiment should have been better—a class at 6, a more solid way to record progress. But if I were to transport myself back in time, I have little doubt my past self would stick to the original plan. Perhaps this is the journey—understanding my limits and taking failure in stride for conversion into wisdom.
