I cannot tell whether I am still learning
For most of my working life I could feel myself getting better at this.
There was proof. A job that frightened me once, and then the next one did not. A log I used to read line by line, and then could read in one look. The work got easier in a way I could point at, and that was the pay I kept, more than the invoice.
That has stopped, quietly enough that I never saw the evidence go.
What I build now comes out better than I would have done. Tidier, more careful, and it does not forget the thing I always forget. Better than I did on the same job, back when it was all mine. And none of the getting better was me. I cannot name one thing I learned from the last thing I built. I dare say I learned something. If I cannot say what, it is the same as not learning it.
What I did not see coming is the measuring. The only record I ever had of my own progress was the work improving. Take the work out of the count and there is nothing left to measure against. I cannot tell whether I am sharper than I was or just better at asking. I would rather not be asked. Not because the answer is bad, but because I do not know, and it used to be the easiest question in the world.
I am very good at saying what I want now. It was not the skill I set out to get, and nobody would put it on a card.
I keep a corner of the work that only I touch. The small scripts, the shell, the dull bits nobody sees, done the slow way with nothing helping. It is not a better way to work, just the only place left where I can feel the difference between doing a thing badly and doing it well, and that difference is the whole of what the trade taught me.
The rest of it I measure on a climbing wall, where nothing can take the weight for me and I can tell you which move I could not make last time. That is a thin substitute for a trade. It is also the only honest measurement I have.
I am still building. Some of it is better than anything I made before, and I would like to think the difference is me. I cannot prove that any more. Most of what I know now, I could not tell you when I learned it, and that has never been true of me before.
