JAPANESE SAYINGS (aka kotowaza): Binbo hima nashi

貧乏暇なし
びんぼひまなし
Literally: poverty free time lacks
Better: poverty has no free time, poor people have no free time

generally used as a self-deprecating gesture
I'm poor, so I have no free time

(and my friend points out that there is a certain element of pride there, too. I'm so busy -- and undervalued -- that I have no free time)

So... 貧乏暇なし gotta go!
