不要轻易放弃，坚持到底就是胜利。

Success is not measured by profits alone, but by the positive impact we leave behind.

历史学家行走在事实与想象的钢丝上。

The world is not run from where he thinks. Not from castle walls, but from countinghouses, not by the call of the bugle but by the click of the abacus, not by the grate and click of the broadsword but by the scrape of the pen.

I don't let anyone control me.

I always try to be better than I was yesterday.

如果你无法简单地解释它，说明你理解得还不够透彻。

如果你不愿意冒险，就永远不会取得伟大的成就。
