And again, German has a word for it: Zettelwirtschaft. Not sure how to faithfully translate this, but it’s essentially managing information in the form of many paper documents or notes
In this instance I am trying this fairly low tech approach of visualising the remaining work on a goal for that day.
What are these stuck to? Recently I tried using post-its to think through something, but they wouldn’t reliably stick to my wall. 
That’s my flat door. But I do also have a lot on my wall. They stick just fine.
Huh, maybe I need to get some better quality post-its. 
FWIW mine are apparently the “original” Post-its.
they now sell ‘super-strength’ post-it notes in shops / on amazon etc
Marbles also work. Having a dish of marbles (or those glass beads you can get at a dollar store, or dice… or anything, really) in one dish or jar and moving them to the other every time you do a slice of work is a nice way to keep track, too. @dreev has a bracelet that has beads on it that he can slide from one side to another to keep track of things.
I used to have a way overcomplicated set-up that would approximate how much time a goal would need given the units left to do and put an appropriately-sized event into a dedicated calendar. Don’t do that. (Also, I’ll post about it when I inevitably do it again so that if you want to, you can do that.)
I think I may have tried doing this with LEGO’s once or twice… Never seemed to stick, though. Might have to try it again. 
Marbles, hu! That reminds me: I have thought of making something that would send a marble down a track every time I completed a goal, or some slice of a goal. Because physical feedback is 
I blame Martin:
I also find 3D feedback helpful. I should really have my hue lights set up so that they flash blue when I give myself some extra buffer on a goal and red when my goals zeno or something again.
Atomic Habits talks about a salesman that would have 120 paperclips in a cup and for each sales call he made, he’d take one paperclip and put it into another cup. 
Peel them sideways. Not vertically.
I made a thing:
It’s a box to put post-its in!
I meant to make something different but ran out of wood, so I made this instead 
It needs more sanding to get rid of the burn marks and then I’ll slab some vegetable oil on and then it might even look nice.
