If you see something that should be fixed, you fix it. Whatever shouldn’t be fixed, you don’t
"For the most part we’re really ignorant. We try to remedy the things that
shouldn’t be remedied, and it just doesn’t work—because there’s one kind of
stress that should simply be observed and shouldn’t be fiddled with at all. Like
a rusty watch: Don’t polish away any more rust than you should. If you go
taking it apart, the whole thing will stop running for good. What this means is
that once you’ve seen natural conditions for what they truly are, you have to let
them be. If you see something that should be fixed, you fix it. Whatever
shouldn’t be fixed, you don’t. This takes a load off the heart."
