天籁，风吹万窍声音不同，都是自由自在地发声或停止，毋需外力的支配。

我感恩每一刻。

"The moment you doubt whether you can fly, you cease for ever to be able to do it."

Science is not just about theory; it's about making things that work in the real world.

The ability to be alone is the ability to love. It may look paradoxical to you, but it's not. It is an existential truth: only those who can be alone are able to love, to share, to go into the deepest core of another human being—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other.
