The corollary is that you don't improve what you don't measure.

OP's point is, I believe, that you don't know that you're really grokking much of anything and how much it's actually reflected in your work, because you're not measuring it. This can work if you have good feedback mechanism at work, though.

I mean, this is a nice saying, but it is pretty clearly not true. Lots of things that aren't measured are improved; we have not measured my two year olds vocabulary at all, but it is certainly improving.

Indeed. The correct corralary is "Things that don't improve aren't being measured"

E.g. negating A => B yields !B => !A

So measuring learning is a good thing, because it means you will likely be more deliberate in actually getting better at it, as opposed to just leaving it up to chance
