money comes and goes; money circulates

金は天下の回り物だから、今はなくてもまた入ってくるよ。
Money comes and goes, so even if you don't have it now, it'll come back around.
A traditional Japanese proverb. The exact origin is uncertain, but it reflects the idea that money circulates through society and does not permanently belong to any one person.
