“When nothing seems to help, I go and look at astonecutter hammering away at his rock perhaps a hundred times without as muchas a crack showing in it.Yet at the hundred and first blowit will split in two,and I know it was not that blow did it—but all that had gone before.” “当一切看起来都无济于事的时候,我去看一个石匠敲石头。他一连敲了100次,石头依然纹丝不动。但但他敲第101次的时候,石头裂为两半。可我知道,让石头裂开的不是那最后一击,而是前面的那一百次敲击的结果。” ---Jacob Riis
