Ale myslíte, že těch stejných kapek úsilí kape na jednu malou spot, možná ne v oceánu, ale na skále. Kapky vody, koncentrované na jednom místě, může se nakonec, že prorazit skály.
But think of those same drops of effort dripping onto one tiny spot, perhaps not in the ocean but on a rock。 The drops of water, concentrated on one spot, can eventually break through that rock。 And if that rock is supporting a lot of other rocks, those drops of water can cause an avalanche。
