When the process works – keep doing it!

…imagine a piece of ground that is really fertile, but it is really fertile because you have a structure for looking after it: feeding it, weeding it, draining it, watering it and a whole heap of other things you need to do to it. But then you assume the ground IS fertile rather than having been made fertile. You stop doing. You assume. You get on with other things. The residual fertility keeps it going for a while but then fertility of the ground quickly fades and you’ve no idea why!
