Technology itself has no value; it only becomes meaningful when it solves real problems.

挡在一个人和他想要的生活之间的唯一东西是尝试的意愿和相信可能的信念。

The only real failure in life is not to be true to the best one knows.

实现明天理想的唯一障碍是今天的疑虑。

译文：感叹白发，观察世间的道路。人们无不追求荣华，看重富贵而轻视贫贱。显赫的宫门，华丽的宫殿。年轻时入仕，幼年时就献上谋略。

The only thing you have to fear is fear itself.
