Yes, but once you have the solution crystalized in your head do you not feel some frustration in not getting it implemented as soon as possible?

I often found myself impatient in getting something I knew would work to actually work, and it was always due to the tiresome fractal of complexities that any non-trivial task involves, like looking up an API or working around the quirks of some dependency.

On a related note, this is also why I find AI-assisted coding so efficient: I have the code visualized in my head to a decent level of detail, and so reviewing the AI's output is a breeze; it's like doing a semantic diff of what I had visualized and what it produced, and so any issues are glaring and easy to spot.
