It's Bav, we speak our own form of Alpine German, like Austria or Switzerland. Much closer to those than to Northern German, so it should be hard to understand for anyone who doesn't live in the Alps. Germans don't understand us, sometimes not even when we try to speak High-German
I don't agree with your either/or theory though, as languages, physics(particle & astro) and music are the subjects I'm best at. I also know my way very well around medicine, geography, history, chemistry, biology, I think one ought not give oneself these ideas, that one would not do well, it's self-limitation at its finest.
At my work (musical pedagogy/therapy) I often hear the following "I just don't have the musical talent", "I don't have the music gene", whatever. While it is true that some have an advantage over others, this advantage doesn't last too long into actually practicing and studying theory, etc. So the best musician is not someone who was fucking talented to begin with, but someone who became so talented by relentless practice. I've seen literal tonedeaf people go from 0 to a hundred with practice. And that makes them so so much better
The same is true for learning anything. The first base that has to be met is interest. If something doesn't interest you, you have no chance of retaining information. Also you need to study efficiently, or it's useless. Try learning something for 5 minutes, and then actively for 10 seconds, do absolutely nothing. Think about nothing, close your eyes, just go blank. Then do another 5 minutes. You will have made better progress than if you would have learned for 60 minutes straight.
