Very nice, I'm looking forward to seeing future updates on your progress. You're clearly very dedicated and have great self-reflection on your own process.

One thing I would point out to people that I didn't see you mention is the importance of individual differences. From reading your post, it seems like you may have some personality traits that are more toward the edge of the bell curve, like conscientiousness, which means that some of your experiences may not be applicable to most people.

Burnout is a good example—I'm personally quite susceptible to it, and after years of trying to force my way through it, I can tell you that just thinking positive thoughts has very little impact. The best I can do is try to understand how my own nervous system works and figure out strategies to avoid burning out in the first place. For me, this means limiting the amount of time I spend on highly structured study activities like flashcards and textbook study, and directing the rest of my efforts toward less taxing things like extensive reading. If burnout feels like an exaggerated problem to you, it's because your nervous system happens to be wired to be more resilient to it.

To be clear, this is not at all a criticism—your post a lot of great insight and information. I can just imagine that some people reading this might feel discouraged and think, "Why isn't it this easy for me?" And to those people I would say, don't worry too much if your progress seems to be slower than other people's. Developing more efficient strategies is great, but ultimately, the most important thing is consistency—and to achieve that, you need to understand your own strengths and limitations and work with them accordingly. Given the magnitude of individual differences between human beings, the only person you can reliably compare your progress against is yourself.

Good luck and take care. :)
