As always, there is "don't make em; don't break 'em."
And whispering as well: Do your best to do no good. Do your best not to improve stuff. Do your best to be honest and be prepared for the lies that are bound to spring up out of the soil.
Do no good is not, as the simple-minded might say, an invitation to self-centered asshole-dom.
Just think a minute. Was there ever a (wo)man with an ax to grind who didn't imagine/insist s/he was doing some good? Do-gooders are a dime a dozen. Improvements abound ... are you shitting me?
Try to be honest. It probably won't work, but try anyway.
Stick with the Dalai Lama: "My religion is kindness."
