True leadership is about empowering others to achieve what they thought was impossible.

——1963年6月25日在西德市政厅柏林墙前的演说

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

Ignorance is not innocence but sin.

"The true measure of a writer's success is not in the accolades received, but in the hearts touched."
