True leaders don't create followers; they create more leaders.

"The only thing we have to decide is what to do with the time that is given us."

科学是人类认识世界、改造世界的强大武器。

The only limit to our realization of tomorrow is our doubts of today.

译文：假如你命中富贵荣华，也要常常有不得意的想法；假如你碰到境遇顺利，也要常常有不如意的念头；假如眼前的你吃穿丰足，也要保持节俭不忘贫困；假如别人都很喜欢你，也要常常怀着谨慎的想法；假如你家世名望都很高，也要常怀着谦虚卑下之心；假如你的学问非常高深，也要提醒自己掌握的还不够多。

The piano is like an old friend to me.
