37signals (I believe this is excerpted from a Jason Fried interview):
Slow time is “Maybe it takes two or three days to have this conversation. And we do it over periods of 15 minutes here, two minutes there, four minutes there.” And that’s fine. It doesn’t need to happen all at once. Unless it’s really, incredibly, truly urgent. (Which most things aren’t. They’re made out to be that way, but they really aren’t that important.)
Read the parenthetical again.
