One lesson from farming and waterwork that I've tried to inculcate in myself is continual incremental improvement because nothing stays perfect.
In farming, something is always broken or less than it should be. But there is literally not enough time in the day (or money) to fix and maintain everything perfectly. So you do the best you can.
Similarly, in waterwork, the ocean beats the hell out of everything. Docks, boats, houses, machinery, etc. And so why fix that solid but beat-up dock, if there's a chance this year brings the hurricane that rips it away? Functionality is more important than form.
