And also (and also, harder to see) is the invisible infrastructure trail that accrues.

Have you ever spilled something sweet and then found a trail of ants snaking from your dropped jam to some distant lair outside? Something like that, I think -- the channel flows, the capital allocation, the tendrils being sent out, knitting into pores of the brick. And so, too, for the mental infrastructure slowly built out and reinforced.

Hard to assess, but real. So def worth doing and caring about. But maybe valuable in a different way than we usually think.
