I don't let negativity define me.

The destiny of world civilization depends upon providing a decent standard of living for all mankind.

Every ton of coal we extract carries equal weight in responsibility.

The principle goal of education is to create men who are capable of doing new things, not simply repeating what other generations have done.

We are all bound by the laws of our own natures.

Every seed we plant carries the potential to transform lives.

写作是一种生活方式，一种存在于世界的方式。
