Short, practical notes on learning a language by producing it. One idea per note, and no worked examples in any single language, because the principles hold in all of them.
One sentence. Set the bar low enough to be boring, then never miss it, because the days you planned for aren't the days you get.
Fifteen or twenty errors, in any language, for years. A list that short is fixable. It survives because nothing writes it down.
The first three feel productive. You read the fix, it makes sense, you move on. Then it comes back, and nothing connected it to the last time.
You can accumulate hours by being in the room. You cannot accumulate sentences that way, which is exactly why they are the better number.
You are not learning more slowly. You are reaching for the same few hundred words every day, and they keep working.
Waiting for enough grammar is how people stay stuck for years. What grows while you wait is comprehension, and it does not transfer on its own.
and the practice itself:
One prompt a day, one sentence back, corrected, with the errors you repeat kept on a list
until they stop.
