No, you're right, and I should have set the expectation that you can't really get into deep thinking mode that more demanding tasks require.

But a lot of it can be discrete or boilerplate. While it's not muscle memory yet, leaving comments for myself and implementing them later, especially when it's about implementing $routine in $language. This is useful when learning.

Doing integration work will take focus or great planning + notes though. But I think it can be done to a large extent. I find it easy to pick up old abandoned projects where I've left enough comments to my future self.

And I'm in my 30s now so not the youngest in software either.
