One I use when describing someone who’s off in his own little world or otherwise not paying attention:
“He’s gone out to lunch and stayed for Happy Hour.”
Nitpick: Corsica had it earlier. Man named Paoli, after whom a suburb of Philadelphia was named, from which I infer that the Americans really did know about it. It was overthrown by a man named Bonaparte (who had a son named Napolean, who achieved a certain fame). But I really like your aphorism.
My own contribution: A rising tide raises all yachts. (And swamps all those boats stuck in the mud.)
“YODO! (You only die once)”
For the risk adverse.
When someone was applying praise to me at work a little too effusively:
Save your butter for your toast.
Of course it depends on how you say it. I tried not to make it ungracious. It was to my boss, and she wrote it on her Wall O’ Sayings.
That reminds me of two others.
To “feed someone shit and tell them it’s buttered toast,” meaning to tell someone a lie, especially an elaborate, long-winded lie to save your own skin.
“You buttered your bread, now you have to lie in it,” a saturated fat variation on *you made your bed, now you have to lie on it. *
If power is lost, restore power. If power cannot be restored, move to an area where there is power.
