I think I track learning too much like a todo list

Lately I realized I track learning almost the same way I track tasks.

Watch this video.
Read this doc.
Finish this course section.
Build this small thing.

I check things off, and it feels good for a minute.

But a few days later, I still have the same question:

Did I actually get better, or did I just finish some stuff?

For coding, this feels especially weird.

I can spend a week jumping between docs, bugs, tutorials, Stack Overflow answers, and little experiments. By the end of the week, I definitely
did things. But it is not always clear what improved.

Maybe I understand async a bit better.
Maybe I got faster at debugging CSS.
Maybe I learned one database concept.
Maybe I just watched too many videos.

A todo list does not really show that.

I have tried notes, Notion pages, spreadsheets, and GitHub commits. They all help in some way, but they still feel more like a record of
activity than a record of skill growth.

I am not sure what the better system is yet.

Maybe it is a weekly review.
Maybe it is tagging learning by skill.
Maybe it is some kind of visual map.
Maybe it is just writing better notes.

Curious how other people think about this.

When you learn something technical, do you track what you finished, or do you try to track what you actually got better at?
