我在大学的时候，一直想参与做能够改变世界的事情。而现在我就在做这样的事情。

If a Nation expects to be ignorant and free in a state of civilization,it expects what never was and never will be....If we are to guard against ignorance and remain free,it is the responsibility of every American to be informed."

我们成功的衡量标准不仅仅是开采的吨数，还有社区的提升。

你唯一应该努力超越的人就是昨天的自己。
