here's what will happen. the oak standing on a hillside is exposed to every storm and gale. as a result its roots plunge deep into the earth and spread in every direction, even wrapping themselves around giant boulders. at times it may seem the tree isn't growing fast enough—but the growth is happening underground. it's as if the roots know they must ported the tree from the threatening elements.
事情的结果便是这样。那颗长在山上的橡树经历了大风大雨，结果它的根深深地扎进了泥土中间，并不断向四周扩张，甚至把自己置身于巨大的石块当中。有时它可能看起来长的不是很快，但这时它却在地下悄悄生长着，好像它的根知道自己必须快速生长来保护树木免受自然危害的影响。
if you want to understand adversity, take two identical acorns from the same oak tree and plant them in two different locations. plant the first in the middle of a dense forest, and the other on a hill by itself.
如果你想理解什么是逆境，就去拿两颗从同一棵树上摘下来年龄相同的橡树果，并且把它们种到不同的地方。第一颗种在浓密的树林当中，而另外一颗则单独种在一座山上。
