I understand what you're trying to do, and I do appreciate it, but this statement is somewhat absurd to me. Sunk-cost after a week and a half? Techniques to improve your ability to achieve your goals are necessarily bullshit?
how much of my time should be dedicated to developing this expertise?
Apparently the correct answer to this question is two to four hours a day with some amount of breaks between sessions. More is better here, but even the best deliberately practice fewer than four hours a day due to greater amounts decreasing motivation. As one might imagine the way we practice is significant, and I have some tips with respect to this as well.
how does one maintain passion and industry for something in particular?
The solution to the first question is likely part of the answer to the second as I typically work more than four hours a day on a topic when I dedicate myself to it. I also have learned several techniques nearly of relevance to this point. Nothing to really address the things in its self.
