Is there any rationalist equivalent of "good luck"? I've tried a few variants, such as "work well", "knock them dead", "we're with you" and certain situation-specific phrasings, but haven't found anything that worked generally - though a hearty "may all the gods of Olympus be with you!" can serve. Not a vitally important point, but it would be nice to have something similarly supportive and yet accurate to say.
Choose well is a nice salutation for instrumental rationality. But what about, "Know much and choose well" to cover epistemic and instrumental rationality?
"Freeze long and proper" for the cryonically inclined Trekkies.
