水压随水深而增大
这是一幅画，画的是水龙头下有3个孔的高高圆筒，水不断从水管通过龙头流入圆筒。因为筒上有3个孔，圆筒永远装不满，水不断泄出。
从水自孔中流出的情况，可以看到压力随水的深度而增大让我们看圆筒顶上的第1孔。因为离水面近，顶部的水压不如中间和底部的水压大。水从孔里成30度角涌出，落到离圆筒不远的地方。
再看中间的孔。这里离水表面深一些，水较深，压力也较大。因此，水成45度角，以较大的力落下。
最后，但不是最不重要，请注意底部的孔。因为在底部深处，水压最大，流出孔时水力最强，成170度角冲出，落到离圆筒很远的地方。
现在，我明白了人为什么能在有巨大压力的情况下获得成功的道理。亲爱的朋友，不要害怕压力。压力越大，成功的机会就越多。
