从长远来看，未来是由乐观主义者决定的。成为一个乐观主义者，不是要忽视现有的许多问题，而是想象怎么才能改善我们解决问题的能力。

The world is the totality of facts, not of things.

Come,my friends,Tis not too late to seek a newer world,For my purpose holds to sail beyond the sunset，And though we are not now that strength which in old days moved earth and heaven,That which we are, we are;-- One equal temper of heroic hearts, Made weak by time and fate, but strong in will. To strive, to seek, to find, and not to yield。

The most successful societies in the world are those that have been able to combine the strengths of the market with the strengths of a strong state.

坚毅是对长期目标的激情和坚持。
