Of course, you can always choose to learn something you aren't best at, but at least you know the trade offs (i.e. needing to spend relatively more time to reach the same level of competence as more talented person).
You just have forgotten what it is like to be a child who knows nothing. I've been speaking English since I was a toddler, I'm learning Spanish now and I make tons of mistakes and often can't understand even a basic sentence - but in fact I'm a lot better at Spanish than I was at English when I had equivalent amounts of study into English.
Once you are a minimal level of competency it is a lot easier to study as well. So if you have only a tiny head start you will be top of your class, and that is always more enjoyable.
....That doesn't track.
If there is such a thing as lack of talent, then "talent" is just "not lack of talent".
The mental sphere is where it becomes super vague for me. Did John Von Neumann just study really hard? The anecdotes told about Feigenbaum of Chaos Theory make him sound like a savant among savants. They just kept that childlike curiosity? Doesn’t make any sense to me. It seems they are tuned differently.
