🔧 Method — why speed at all
Some years ago at a talk, a businessperson said that raising revenue ten times over is easier than raising it two or three times. It sounded like wordplay until he explained it, and once explained it stopped being about revenue at all. It reads as a description of how most people study a language.
Before any of the argument, here is the concrete thing underneath it. Nothing about willpower — just a count of what goes past your ears.
To get two or three times the result out of the method you are already using, you have to put in two or three times the effort. Thirty minutes a day becomes ninety. For anyone with a job and a family that hour is usually not available, which is why the resolution to try harder tends to collapse within about three weeks. Not weak will — impossible arithmetic. And the resolution is quietly expensive while it lasts, because it spends the one thing you cannot make more of.
Walking for two hours is good for you and builds very little leg muscle. Five minutes of squats builds some. The difference is not the time spent but the kind of load. Listening is the same: an hour at a comfortable speed and ten minutes at a speed you can only just hold are not the same exercise, and they do not produce the same thing. Longer is not a stronger version of harder.
① Speed. Not a pace you can follow comfortably, but one you can only just hold — the load has to be a load. ② Order. Not the new language first, but a language whose meaning already costs you nothing, played fast, so the ear learns the tempo before it has to learn the sounds. ③ The target. Following half of a line counts as a success, instead of understanding all of it; going back for the word you missed is what loses you the rest of the sentence. None of the three asks for more hours. Each asks the same hours to do a different job. (If the language you are learning happens to be Korean, our free course is built on that second point — brain-hz.com/korean, 60 lessons, shadowing and speak-first modes, uncompressed audio, free and no account.)
The slogan version of this idea is empty because it never names what to change. Ours is narrow enough to argue with: play the sound faster than you can comfortably follow, start in a language you already understand, and accept half. You can reject any of the three specifically, which is the point of writing them down rather than saying “change your approach”. The case for the order is in [[listening-first-order]]; the drill itself is described in [[what-is-shadowing]].
“Change the method and the result changes” and “the result is n times better” are not the same claim. The second one belongs to whoever did the measuring, and we have not measured. So no learning multiplier appears in this article, or in any other one here — where you see a number on this site it is a playback speed, not a rate of improvement. What we took from that talk is a direction rather than a figure: instead of pushing harder along the same road, change the road.

The line came from a talk and we could not verify it in any public record, so the speaker is not named. This is the practical half of [[three-thousand-hours]], which does the arithmetic on the hours; the order is argued in [[listening-first-order]] and the drill in [[what-is-shadowing]]. — Not carried over from the Korean edition: the original blog post’s “nine times” and “ten times” learning efficiency, its use of a memory researcher’s work as a multiplier for study efficiency, and its “your ears will open twice over in 30 days”, none of which we could trace to a measurement.
