I like to do deep dives like this not to memorise but to understand deeper layers, the spirit of the language, the way it moves, the way it unfolds.

By all means, it is fun to play with a language. And every person's brain works differently.

I like to use this metaphor, though. You're hiking a mountain, this journey to the "peak" is reaching some goal of fluency.

It's fun to stop and look at rocks, examining, comparing and whatnot. But it doesn't necessarily get you closer to the peak. I mean, it might, because you'll better understand your footing every-so-slightly. Not a perfect metaphor.

Thanks! Feels like the only person on this page who gets what I was going for.
