Thank you, that's a good metaphor, I'll remember that. I feel like I got just to the point where the trees along the bank of a river had been cut down, so the soil had begun eroding and the water table was dropping. Luckily (in a way) I'm off that project and beavers have moved in and started building dams, and it may take a while but the ecosystem in my brain seems to be recovering, albeit slowly :-)
