2) Is learning any topic easier for you than for an average person or are you so talented in just a few areas?
At least for me, this also comes with costs. Some of these costs are immediately observable to me (much lower levels of broad-insight / Gordian-Knot-slicing, and I am less patient with others). Other costs are only presumed…I have guesses about associated long-term health risks both direct and indirect.
Anyway, all this to say, I think it can be done artificially. Since these things take time to play out towards mastery, you better hope you can get it right. Just like in software, some things can be a Pareto improvement, but some things can be prematurely optimized, and some things really never needed to be built in the first place.
I agree about inputs. I have a list project I'm working on called "This I Believe". I'm trying to decode my deeply held beliefs so that I understand mself and can change those beliefs. The very first thing I put on it was "Better living through chemistry."
