積水成河
personally speaking,i'm strongly in favor of this idea.never should we make light of the power of small things whatever it is.
when it comes to good things,don't hesitate to do it even if it seems too small to amount anything.truthfully,every skyscraper is composed of bricks.
as for evil things,ignoring the tiny negative affect could result from the tiny beginning.
thus,i suppose that we are supposed to do good things and avoid engaging in evil even if it is small.the affects of them can hardly be ignored.
