At 33 I’m feeling something similar. I wouldn’t say that new subjects are hard, necessarily, but they do take a type and quantity of mental energy that’s not always available, making for a sense of tiredness in these situations.
I could be wrong but I feel like this would improve a lot if I didn’t have to work a job for a while. The bulk of each day’s mental energy goes into writing code, which doesn’t leave much for other things.
Same age, same boat but I wonder about two independent factors: how my cumulative health decisions have depleted my energy reserves, and if being lower on the Dunning-Kruger curve had some distinct advantages earlier in life (i.e. I expect things to be harder now which adds an additional mental obstacle and fatigue). I also gave a shit about far less thus further freeing mental capital.
Then again, outside of sports, nothing in my youth was taxing (particularly not school). The only real mental investment I had to make was verbal sparing with friends, and video games.
It was easier to do math in my head but I had been doing it regularly for years (full stack web apps call for very little), and it was much easier to keep momentum on something like Tolstoy (could also be health related though).
What about you? Any specific things you think you could incontrovertibly do better in your youth that aren't likely confounded by other variables?
> how my cumulative health decisions have depleted my energy reserves
I wonder about this too. Goodness knows that sleeping for ~4 hours or pulling all-nighters, eating the cheapest things on the shelf, and not getting in much physical activity late in high school and through college weren't sound decisions and are likely to haunt me for the rest of my days.

This isn't that much of a problem for me. In fact when it turns out that things put up less resistance than expected it's kind of refreshing and helps pull me along. The trick is getting to that point in the first place.

Hard to answer, really. Maybe sitting down and getting lost in the process of doing something creative… it came extremely naturally to me in my teens and early 20s but there are so background processes associated with being a responsible somewhat functioning adult running in my head now that it's considerably more difficult. Probably fixed by removing the need for those background processes to run, but that's not exactly practical.
Are you referring to people often misapplying the concept, or its replicability issues (which I had admittedly come across before but don't hold in active memory)?
I'm confident I nailed the former (I thought I was better at things than I was in reality when I was younger, and am now more likely better than I think I am in those same domains today).
If you referring to the latter, it's tricky for me. It's like the famous two humped camel in programming aptitude. It seems to be useful in describing experiential observations but didn't (doesn't?) replicate. I've stopped using it at this point because I don't want to mislead people.
DK also has the appearance of explanatory power at a minimum, and utility in communicating the simple form of the concept. I don't like the replicability issue but wonder how bad the down side is if all I'm really saying is we aren't often humble enough about new things, and aren't confident enough about things we've dedicated time to?
Welp, that justification for promoting something potentially falsifiable surely isn't going to come back to bite me and expose my hypocrisy elsewhere...
